Microsoft Security Advisory (912920)
Systems that are infected with Win32/Sober.Z@mm may download and run malicious files from certain Web domains beginning on January 6, 2006
- http://www.microsoft.com/technet/security/advisory/912920.mspx
Published: January 3, 2006
"Microsoft is aware of the Sober mass mailer worm variant named Win32/Sober.Z@mm. The worm tries to entice users through social engineering efforts into opening an attached file or executable in e-mail. If the recipient opens the file or executable, the worm sends itself to all the contacts that are contained in the system’s address book. Customers who are using the most recent and updated antivirus software are at a reduced risk from infection by the Win32/Sober.Z@mm worm. On systems that are infected by Win32/Sober.Z@mm, the malware is programmed to download and run malicious files from certain Web domains beginning on January 6, 2006. Beginning approximately every two weeks thereafter, the worm is set to begin downloading and running malicious files from additional sites on the same Web domains. As with all currently known variants of the Sober worm, the worm does not appear to target a security vulnerability, but rather relies on the user opening an infected attachment...
Suggested Actions
• Check for and remove the Sober infection.
Use the Microsoft Windows Malicious Software Removal Tool, Safety.live.com, or Windows OneCare to search for and remove the Sober worm and its variants from infected systems.
• Monitor outbound network connections to targeted Web sites.
• Because the Win32/Sober.Z@mm worm may download and run malicious files from certain Web domains beginning on January 6, 2006, attempted connections to the following Web sites should be monitored for signs of an infected host on local networks.
Targeted Web sites
people.freenet.de
scifi.pages.at

Win32/Mywife.E@mm
Published: January 30, 2006
"Microsoft wants to make customers aware of the Mywife mass mailing malware variant named Win32/Mywife.E@mm. The mass mailing malware tries to entice users through social engineering efforts into opening an attached file in an e-mail message. If the recipient opens the file, the malware sends itself to all the contacts that are contained in the system’s address book. The malware may also spread over writeable network shares on systems that have blank administrator passwords.
Customers who are using the most recent and updated antivirus software could be at a reduced risk of infection from the Win32/Mywife.E@mm malware. Customers should verify this with their antivirus vendor. Antivirus vendors have assigned different names to this malware but the Common Malware Enumeration (CME) group has assigned it ID CME-24.
On systems that are infected by Win32/Mywife@E.mm, the malware is intended to permanently corrupt a number of common document format files on the third day of every month. February 3, 2006 is the first time this malware is expected to permanently corrupt the content of specific document format files. The malware also modifies or deletes files and registry keys associated with certain computer security-related applications..."

MS Security Advisory (914457)
Possible Vulnerability in Windows Service ACLs
- http://www.microsoft.com/technet/security/advisory/914457.mspx
Published: February 7, 2006
Microsoft is aware of published information and proof-of-concept code that attempts to exploit overly permissive access controls on third-party (i.e., non-Microsoft) application services. This code also attempts to exploit default services of Windows XP Service Pack 1 and Windows Server 2003. If these attempts were successful, a user who has low user privileges could gain privilege escalation.
Microsoft has investigated these reports and the findings are summarized in the chart below. Microsoft has confirmed that customers who run Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1 are not vulnerable to these issues because security-related changes were made to these service packs as part of our ongoing security improvement process. Users who run Windows XP Service Pack 1 and Windows Server 2003 Gold may be at risk, but the risk to Windows Server 2003 users is reduced.
Users are encouraged to contact their third-party software vendors whose products require services installation to determine if any non-default Windows services are affected.
Microsoft is not aware of any attacks attempting to use the reported vulnerabilities or of customer impact at this time. Microsoft will continue to investigate the public reports to help provide additional guidance for customers as necessary.
Mitigating Factors:
• The latest Microsoft operating systems, including Windows XP Service Pack2 and Windows Server 2003 Service Pack 1 are not vulnerable to these issues.
• A malicious user who launches an attack based on the finder’s report would require at least authenticated user access to the affected operating systems
• Two of the four services identified in the paper (NetBT and SCardSvr) require an attacker to already be running in a privileged security context. Additionally, the two services that do allow an authenticated user to attack are vulnerable only on Windows XP Service Pack 1.
• Firewall best practices and standard default firewall configurations can help protect from attacks that originate outside the enterprise perimeter. Best practices also recommend that personal firewalls be used within a network and that systems connected to the Internet have a minimal number of ports exposed..."

MS Security Advisory (913333)
Vulnerability in Internet Explorer Could Allow Remote Code Execution
- http://www.microsoft.com/technet/security/advisory/913333.mspx
Published: February 7, 2006
"Microsoft is investigating new public reports of a vulnerability in older versions of Microsoft Internet Explorer. Based on our investigation, this vulnerability could allow an attacker to execute arbitrary code on the user's system in the security context of the logged-on user. The attacker could do this by one or more of the following actions:
• By hosting a specially crafted Windows Metafile (WMF) image on a malicious Web site;
• By convincing a user to open a specially crafted e-mail attachment;
• By convincing a user to click on a link in an e-mail message that takes the user to a malicious Web site; or
• By sending a specially crafted e-mail message to Outlook Express users, which they view in the preview pane.
>>> Note This is not the same issue as the one addressed by Microsoft Security Bulletin MS06-001 (912919).
The vulnerability exists in:
• Internet Explorer 5.01 Service Pack 4 on Microsoft Windows 2000 Service Pack 4
• Internet Explorer 5.5 Service Pack 2 on Microsoft Windows Millennium.
The vulnerability does not exist in:
• Internet Explorer for Microsoft Windows XP Service Pack 1 and Windows XP Service Pack 2
• Internet Explorer for Microsoft Windows XP Professional x64 Edition
• Internet Explorer for Microsoft Windows Server 2003 and Windows Server 2003 Service Pack 1
• Internet Explorer for Windows Server 2003 for Itanium-based Systems
• Internet Explorer for Windows Server 2003 with Service Pack 1 for Itanium-based Systems
• Internet Explorer for Windows Server 2003 x64 Edition
• Internet Explorer 6 Service Pack 1 on Microsoft Windows 2000 Service Pack 4
• Internet Explorer 6 Service Pack 1 on Microsoft Windows 98
• Internet Explorer 6 Service Pack 1 on Microsoft Windows 98 Second Edition
• Internet Explorer 6 Service Pack 1 on Windows Millennium Edition
Microsoft has determined that an attacker who exploits this vulnerability would have no way to force users to visit a malicious Web site. Instead, an attacker would have to persuade them to visit the Web site, typically by getting them to click a link that takes them to the attacker's Web site. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems. In an e-mail based attack, customers would have to click a link to the malicious Web site, preview a malicious e-mail message, or open an attachment that exploited the vulnerability. In both Web-based and e-mail based attacks, the code would execute in the security context of the logged-on user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Microsoft will continue to investigate these reports and provide additional guidance depending on customer needs..."

Revision: 5.0
INTRODUCTION
Microsoft is releasing a software update to Microsoft Internet Explorer 6 for Microsoft Windows XP Service Pack 2 and for Microsoft Windows Server 2003 Service Pack 1. This update changes the way in which Internet Explorer handles some Web pages that use ActiveX controls. Examples of programs that use ActiveX controls include the following:
- Adobe Reader
- Apple QuickTime Player
- Macromedia Flash
- Microsoft Windows Media Player
- Real Networks RealPlayer
- Sun Java Virtual Machine
After you install this update, you cannot interact with ActiveX controls from certain Web pages until these controls are enabled. To enable an ActiveX control, manually click the control. There are also techniques that Web developers can use to update their Web pages. For more information about these techniques, visit the following MSDN Web site:
http://msdn.microsoft.com/ieupdate
As part of this Internet Explorer update, Microsoft will release updates to the current versions of Windows XP and of Windows Server 2003. All client operating systems will be updated. These client operating systems include the following:
• Windows XP Starter Edition
• Windows XP Home Edition
• Windows XP Professional Edition
• Windows XP Tablet PC Edition
• Windows XP Media Center Edition
• Windows XP Professional for Embedded Systems
Additionally, updates for earlier versions of Internet Explorer will be released as part of the monthly security update packages.
MORE INFORMATION
Known issues
• Initial logon dialog boxes may reappear and reset to default configurations
This issue occurs if you deploy the hotfix version of this software update on 64-bit systems, such as a 64-bit version of Microsoft Windows Server 2003 with Service Pack 1 or a x64-bit version of Windows XP with Service Pack 2. In this case, the initial logon dialog boxes may appear for applications and for Windows components. Additionally, some settings reset to default. This behavior may cause the following issues:
• Applications ask users to opt in to privacy features.
• Default settings for Internet Explorer favorites are reset.
• Internet Explorer security zones are reset to default settings.
• Internet Explorer advanced settings are reset to default settings.
• Initial Windows Media Player dialog boxes appear.
This is a known issue and is expected to be fixed in the next update for Windows.
• Google Toolbar
You may experience an access violation in the Google Toolbar when you close a window that contains an inactive ActiveX control. Microsoft and Google technical teams have been working together to address this issue. Google is expected to fix this problem by using its automatic "servicing mechanism" for Google Toolbar users. This problem affects Google Toolbar versions before version 3.0.129.2. Visit the following Google Web site to download the latest version:
http://toolbar.google.com
• External script technique does not work when the "Disable Script Debugging in Internet Explorer" check box is cleared
Microsoft is investigating this problem and plans to fix it in a future cumulative update.
• ActiveX controls that use Java Platform, Standard Edition 1.3 or 1.4
After you click on an ActiveX applet control in a program that runs the applet control by using Java Platform, Standard Edition (J2SE) 1.3 or J2SE 1.4, the focus does not go to the applet control. You must click the control a second time to establish focus. The focus behavior works correctly in J2SE 1.5. To obtain the latest version of J2SE, visit the following Sun Microsystems, Inc. Web site:
http://java.sun.com/j2se
For recommended techniques to make sure that ActiveX controls function without user interaction, visit the following MSDN Web site:
http://msdn.microsoft.com/ieupdate
The following issues occur on Web sites that do not use the recommended techniques.
Note: All these issues are resolved by using the techniques that are described on the MSDN Web site.
• Scrolling
When you use the mouse wheel to scroll through a page that contains an interactive control, the control may not be displayed correctly. Microsoft is investigating this issue and plans to fix it in a future cumulative update.
• Abstract Window Toolkit
Access violations have been reported with Java programs that use Abstract Window Toolkit (AWT) classes in the user interface. Microsoft is investigating this issue and plans to fix it in a future cumulative update.
• Transparent Flash
A full-page ad disappears, but the focus rectangle remains. In this situation, the control is still there, but it is transparent. Therefore, the associated overlay window remains on the page.
• DHTML menus
When a DHTML menu is expanded, the menu may appear on top of an ActiveX control. If you click the menu in this situation, you enable the control instead of gaining access to the DHTML menu. The overlay window has the highest z-order. Therefore, this window receives the mouse-click message.
• Controls that prompt before they are loaded
When certain controls are loaded on a Web page, the controls are not correctly masked by the functionality of this update. These controls include controls that are used in Macromedia Shockwave Director, in QuickTime Player, and in Virtools Web Player. When Windows determines that a control is inactive, the system prompts the user before the control is loaded.
• CSS attributes on controls
Controls that are hidden or that have a display-mode setting of None, but that do have size dimensions, display the focus rectangle when you move the pointer over them.
The third-party products that this article discusses are manufactured by companies that are independent of Microsoft. Microsoft makes no warranty, implied or otherwise, regarding the performance or reliability of these products..."

Microsoft updates IE after patent spat

Story last modified Tue Feb 28 17:38:18 PST 2006
"... Microsoft is modifying IE to shield itself from liability in a long-running patent dispute with Eolas Technologies and the University of California. Microsoft expects a second trial in the case to start sometime this year after a federal appeals court last March partially reversed a lower-court decision that exposed it to more than $500 million in damages. In September, the U.S. Patent Office upheld the validity of the patent at issue in the case. Microsoft is delivering the IE update in phases. The company last December said it would make the tweaks and a month later made the update available on MSDN, its Web site for developers. The update is now available to the general public as an optional download via Windows Update and Microsoft's Download Center Web site. "Microsoft expects the vast majority of existing IE customers will download the update as part of ongoing security updates in the next four to six months," the Microsoft representative said. The update is available for IE 6 on Windows XP with Service Pack 2 and Windows Server 2003 with SP 1, the Microsoft representative said."

MS06-012: Critical Vulnerability in Microsoft Office, KB905413
This update fixes a number of different Excel vulnerabilities, and a "Malformed Routing Slip" vulnerability which affects muliple Office components. All the vulnerabilities come down to the same issue: If you open a malformed file, an attacker could get control of the system as the user opening the file. If you use Microsoft Office, you should apply this patch quickly.

MS06-011: Priviledge Escalation in Windows (Important)
It may be possible for a regular user to obtain the privileges assigned to a service. A lower privileged user could change the configuration for a service in order to have it execute code or modify the system in other ways, once the service is running at the higher privilege (e.g. 'system').
This vulnerability has been disclosed for a while now. It is important to note that a "service" is not just a "server". Services typically have to run at a higher privilege level as they require access to files across multiple users, and access to system resources..."

"There is a new and unpatched vulnerability with exploit code in the wild that affects the latest version of IE. The exploit works by including an abnormally large (a couple thousand) number of script actions inside a single HTML tag. This will cause a memory array to write out of bounds and cause an immediate or eventual browser crash. Both McAfee and Symantec have released signatures to detect this exploit. While this is only a DoS vulnerability at the moment, there are ongoing attempts to try to use this as a vector for remote code execution.
More as it develops..."

IE exploit on the loose... InfoCon to Yellow

"...it didn't take long for the exploits to appear for that IE vulnerability. One has been making the rounds that pops the calculator up (no, I'm not going to point you to the PoC code, it is easy enough to find if you read any of the standard mailing lists), but it is a relatively trivial mod to turn that into something more destructive... For that reason, we're raising Infocon to yellow for the next 24 hours..."

Microsoft Security Advisory (917077)
Vulnerability in the way HTML Objects Handle Unexpected Method Calls Could Allow Remote Code Execution
- http://www.microsoft.com/technet/security/advisory/917077.mspx
March 23, 2006
"Microsoft has confirmed new public reports of a vulnerability in Microsoft Internet Explorer. Based on our investigation, this vulnerability could allow an attacker to execute arbitrary code on the user's system in the security context of the logged-on user. We have seen examples of proof of concept code but we are not aware of attacks that try to use the reported vulnerabilities or of customer impact at this time...
Mitigating Factors:
• In a Web-based attack scenario, an attacker would have to host a Web site that contains a Web page that is used to exploit this vulnerability. An attacker would have no way to force users to visit a malicious Web site. Instead, an attacker would have to persuade them to visit the Web site, typically by getting them to click a link that takes them to the attacker's Web site. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.
• This vulnerability could not be exploited automatically through e-mail or while viewing e-mail in the preview pane while using Outlook or Outlook Express Customers would have to click on a link that would take them to a malicious Web site, or open an attachment that could exploit the vulnerability.
• An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights...
FAQs...
- Is this a security vulnerability that requires Microsoft to issue a security update? Yes. Microsoft will release an update for this issue in an upcoming security update release.
- What causes this threat? When Internet Explorer displays a Web page that contains certain unexpected method calls to HTML objects, system memory may be corrupted in such a way that an attacker could execute arbitrary code. Specifically, the public postings discuss a potential behavior in Internet Explorer in the way that HTML objects may handle an unexpected createTextRange() method call to an HTML object. A Web page that is specially crafted to exploit this vulnerability will cause Internet Explorer to fail. As a result of this, system memory may be corrupted in such a way that an attacker could execute arbitrary code..."

"... There are several sites that have been compromised and now contain the exploit code. These sites all run the exploit code and get a file called ca.exe which in turn gets a file called calc.exe and installs it. It is calc.exe that we want to focus on briefly.
This malware installs a dll that is used as a Browser Helper Object (BHO) and also runscopies itself to directory you see below as nm32.exe and runs as a process. The malware creates the following on install:
C:\WINNT\fyt\mn32.dll
C:\WINNT\fyt\nm32.exe
C:\WINNT\fyt\~ipcfg636
C:\WINNT\fyt\~start636
C:\WINNT\fyt\~tmp636
C:\WINNT\fyt\~view636
It also creates one called sub.txt when you surf the internet and records everything that it can about where you surf and do and any information it can get... the individual seems to realize that folks are on to them. I'm pretty sure that the malware has just been changed since its easier to modify the malware and where it FTPs to than to go back to all the hacked sites..."

Email attachment vector for IE createTextRange() Remote Command Execution

Last Updated: 2006-03-26 14:24:42 UTC
"Do You Want To Open This File?
Just for the sake of clarity, there is an email attachment vector for this exploit that's not widely reported. I have not seen any reports of it being used at this time. MS's bulletin, in the FAQ's, in "Could this vulnerability be exploited through e-mail?", says it can be exploited if one "open(s) an attachment that could exploit the vulnerability." ISS obliquely says attacks may occur by "...simply embedding the required logic in specially crafted HTML emails.".
MS doesn't have a bulletin description specific to malicious email attachments, but one of their global workarounds includes prompting or disabling active scripting in the Local intranet security zone, which addresses a malicious attachment exploit in this situation. In addition, keeping gateway email AV sigs up to date is advisable..."

Updated: March 29, 2006
"...Will the security update addressing this issue contain the changes detailed in Microsoft Security Advisory 912945 – Non-Security Update for Internet Explorer?
Yes. However, to help enterprise customers who need more time to prepare for the update, Microsoft will be releasing a Compatibility Update, to be available the same day as the next IE Security Update. Once deployed, the Compatibility Update will temporarily return IE to the previous functionality for handling ActiveX controls. This Compatibility Update will function until an IE security update is released following the April security release, at which time the changes to the way Internet Explorer handles ActiveX controls will be permanent...

"While users wait for Microsoft to patch the most recent zero-day vulnerability in Internet Explorer, security experts agree that the best way to protect PCs is to dump the browser's Active Scripting function. Even eEye Digital Security, one of two commercial security vendors that has released unsanctioned, temporary patches for the problem, said so. "Organizations should only install this patch if they are not able to disable Active Scripting as a means of mitigation," eEye warned in the advisory accompanying the patch. Microsoft's preferred workaround for the createTextRange bug is to disable Active Scripting so as to bar any JavaScript code from running. In fact, this isn't the first time that Microsoft has urged users to switch off Active Scripting; in early December, it used the same advice when another unpatched vulnerability was wreaking havoc.

Here's how to turn off Active Scripting:
-- In Internet Explorer, click Internet Options on the Tools menu.
-- Click the Security tab.
-- Click Internet, and then click Custom Level.
-- Under Settings, in the Scripting section, under Active Scripting, click Disable, and then click OK.
-- Click Local intranet, and then click Custom Level.
-- Under Settings, in the Scripting section, under Active Scripting, click Disable, and then click OK.
-- Click OK two times to return to Internet Explorer.

Doing so, however, will break some sites and/or functions within sites, as Microsoft itself warned in the security advisory posted last week and updated Wednesday. "Disabling Active Scripting in the Internet and Local intranet security zones may cause some Web sites to work incorrectly," the advisory went. "If you have difficulty using a Web site after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly."

"...UPDATE 1: Some readers have written in to express their unhappiness that the non-security-related patch done for legal reasons is being released with the fix for the zero-day IE flaw. I agree. I don't like to see them together either. Consider your complaint on that registered with the ISC, not that we can do anything about it."
