Microsoft Security Advisory (2880823)
Deprecation of SHA-1 Hashing Algorithm for Microsoft Root Certificate Program
- http://technet.microsoft.com/en-us/s...visory/2880823
Nov 12, 2013 - "Microsoft is announcing a policy change to the Microsoft Root Certificate Program. The new policy will no longer allow root certificate authorities to issue X.509 certificates using the SHA-1 hashing algorithm for the purposes of SSL and code signing after January 1, 2016. Using the SHA-1 hashing algorithm in digital certificates could allow an attacker to spoof content, perform phishing attacks, or perform man-in-the-middle attacks.
Recommendation: Microsoft recommends that certificate authorities no longer sign newly generated certificates using the SHA-1 hashing algorithm and begin migrating to SHA-2. Microsoft also recommends that customers replace their SHA-1 certificates with SHA-2 certificates at the earliest opportunity. Please see the Suggested Actions section of this advisory for more information..."
Microsoft Security Advisory (2868725)
Update for Disabling RC4
- http://technet.microsoft.com/en-us/s...visory/2868725
Nov 12, 2013 - "Microsoft is announcing the availability of an update for supported editions of Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, and Windows RT to address known weaknesses in RC4. The update supports the removal of RC4 as an available cipher on affected systems through registry settings. It also allows developers to remove RC4 in individual applications through the use of the SCH_USE_STRONG_CRYPTO flag in the SCHANNEL_CRED structure. These options are -not- enabled by default.
Recommendation. Microsoft recommends that customers download and install the update immediately and then test the new settings in their environments. Please see the Suggested Actions section of this advisory for more information..."
Microsoft Security Advisory (2862152)
Vulnerability in DirectAccess Could Allow Security Feature Bypass
- http://technet.microsoft.com/en-us/s...visory/2862152
Nov 12, 2013 - "Microsoft is announcing the availability of an update for all supported releases of Windows to address a vulnerability in how DirectAccess authenticates DirectAccess server connections to DirectAccess clients. An attacker who successfully exploited the vulnerability could use a specially crafted DirectAccess server to pose as a legitimate DirectAccess Server in order to establish connections with legitimate DirectAccess clients. The attacker-controlled system, appearing to be a legitimate server, could cause a client system to automatically authenticate and connect with the attacker-controlled system, allowing the attacker to intercept the target user's network traffic and potentially determine their encrypted domain credentials. Microsoft is not aware of any active attacks that are exploiting this vulnerability as of the release of this advisory.
Recommendation: Microsoft recommends that customers apply the update immediately using update management software, or by checking for updates using the Microsoft Update service.
Note: In addition to installing the update, additional administrative steps are required to be protected from the vulnerability described in this advisory. Please see the Suggested Actions section of this advisory for more information..."

XP update locks machines with SVCHOST red lined at 100%: Fix it with KB 2879017...
- http://www.infoworld.com/t/microsoft...2879017-230733
Nov 13, 2013 - "... when Windows Update accesses the Microsoft website to gather a list of available updates, the machine can lock up for five, 10, 15 minutes - or more - with the CPU and fan running at 100 percent. Then, if the customer waits long enough for the updates to appear, and clicks to install them, the XP machine goes racing away again for another five or 10 or more minutes, with the CPU redlined at 100 percent... The best solution appears to be a manual update to Internet Explorer. Yes, Microsoft has messed up wuauclt.exe so badly that it has to be repaired by installing an IE update - not a Windows update - to get it working properly. The fix is part of the October cumulative IE patch known as MS13-080/ KB 2879017*. If you manually download and install the October cumulative patch, then you should be able to use Windows Update with no problems... You would think that simply upgrading to the latest version of IE would solve the problem, but it doesn't. You have to manually download and apply the patch for your version of IE..."

MS to fix XP update SVCHOST redline issue 'soon'

Nov 15, 2013 - "... The Microsoft Update team has analyzed the latest manifestation, come up with an explanation, and has promised that a permanent solution will arrive "as soon as possible." Windows Update team member Doug Neal has just posted a message to the Patch Management Mailing List that explains what's happening when Windows XP's Windows Update agent, wuauclt.exe (running in a SVCHOST wrapper), drives CPU utilization to 100 percent - and can keep WinXP machines pegged at 100 percent for -15- minutes or longer.
'The problem is caused by the Windows Update client evaluating an exceptionally long supersedence chain - something IE6 and IE7 have more than any other version of IE due to their time in market. Each 'link' in the chain doubles the CPU resources needed to evaluate it over the previous version. The chain is so long that the design stymies the WUA client.'

'While I can't provide a date for when this will be done, we know it's an issue affecting customer PCs and we're working to get it out as soon as possible to halt the impact'..."

Nov 18, 2013 - "... Microsoft didn't solve the problem, but it did publish a list of video drivers thought to conflict with the patch. The company also modified the installer to avoid planting the font-busting patch on machines running the identified bad video drivers. That list, toward the bottom of article KB 2670838*, has gone through -eight- major revisions... seeing complaints all over the Web that installing Internet Explorer 11 on Windows 7 can -trigger- the same problem - and the fuzzy fonts appear even on machines that aren't running any of the identified problematic video drivers... also seeing reports that the fuzzy fonts crop up on Firefox, Chrome, and - remarkably - Internet Explorer itself. Some people report that the fuzziness goes away if the pages are refreshed enough times. Others see fuzzy characters only on some pages, but very similar pages don't have the problem. If you have a case of the font fuzzies and are using IE10, the only known solution involves uninstalling KB 2670838. But if you've installed IE11, you may or may not have KB 2670838 - and if you do have it, uninstalling doesn't fix the problem..."
