    Qualys analysis: https://blog.qualys.com/laws-of-vuln...nd-to-the-year
    Dec 12, 2017 - "This December Patch Tuesday is considerably lighter than last month’s patch releases. While only three of the fixes were for Windows operating system, the majority of the vulnerabilities to pay attention to are Browser/Scripting Engine based. For an overview, we show fixes for 32 unique CVEs addressed, with 19 Critical, and 24 addressing remote code execution at varying severity levels. No active exploits are listed by Microsoft again this month. From a prioritization standpoint, again we turn our focus to the browsers and the Scripting Engine Memory Corruption Vulnerabilities. We recommend prioritizing patching for user facing workstations to address the 19 Critical Internet Explorer and Edge updates released today by Microsoft, as they are listed as “Exploitation More Likely”. There are no known exploits as of yet, but this is an opportunity to remain ahead of any future exploits that may be released.
    There is one Windows OS vulnerability that should be reviewed, and that is the fix for CVE-2017-1885, which is a Remote Code Execution using RPC on systems that have RRAS enabled. Make sure you are patching systems that are using RRAS, and ensure it is not enabled on systems that do not require it, as disabling RRAS will protect against the vulnerability. For that reason it is listed as Exploitation less likely, but should get your attention after patching the browsers. Additionally, we recommend you take some time to review ADV170021, a Defense-in-Depth update that has configuration options to allow you to exert more control over DDE behaviors, in light of the recent DDE exploits that have been publicized. Note that this configuration change would be made after installing the update referenced in the advisory.
    It should also be noted that on December 7, Microsoft released an out-of-band emergency patch for CVE-2017-11937 and CVE-2017-11940, which was a flaw in the Microsoft Malware Protection engine that could allow an attacker to create a specially crafted file that would be scanned by the Malware Protection engine, allowing for code execution on the endpoint. The patch was automatically ingested by the affected engines via definition updates, so no action should be required. As a precautionary measure, if you are using Microsoft’s Malware Protection engine in Defender, Security Essentials, Forefront Endpoint Protection, or the engines in Exchange 2013 or 2016, ensure that your updates are being applied automatically, and that you are on at least Version 1.1.14405.2 of the Malware Protection Engine.
    From the Adobe side, there was only one Flash update, APSB17-42 listed as a “Business Logic Error”. So all in all, a rather quiet end to a busy year in vulnerabilities..."

    Thumbs down Win7 updates get bigger

    FYI...

    Win7 updates get bigger
    ... monthly security rollups for Windows 7 have almost -doubled- in size
    > https://www.computerworld.com/articl...ng-bigger.html
    Dec 14, 2017 - "... At the 12-update pace that Windows 7's rollups have established, the 64-bit version will weigh in at approximately 350MB by October 2018, and a year after that, as Windows 7 nears its expiration date, almost 600MB. The latter would represent a 20% boost above and beyond Mercer's target size. Likewise, the x86 edition would increase to 216MB and 374MB in 2018 and 2019, respectively, if the 12-update growth rate continues:
    > https://images.idgesg.net/images/art...4368-large.jpg
    ... The 64-bit security-only for July was just 30MB and the 32-bit was an even smaller 19MB, compared to the same month's rollups of 194MB and 119MB. The differences in December were even starker: 900KB and 1.4MB for the 32- and 64-bit security only updates, respectively, and 125.1MB and 204.7MB for the rollups. The rollups are larger not only because they drag their past with them - each succeeding rollup includes that month's patches as well as all previous patches back to October 2016 - but because they also include non-security bug fixes. Usually, though not always, issued later in each month, the non-security updates are bundled with the security patches, adding to the size of the rollup..."

    Dec 18, 2017 - "Some subset of users of Windows 10 Fall Creators Update, version 1709, report persistent bugs with this month’s Patch Tuesday missive, KB 4054517. Many of those reporting problems are using recent Surface devices. Microsoft has not acknowledged any problems... doesn’t seem to explain all of the problems that people are encountering, but it may account for some. Microsoft, as usual, has not confirmed the problem and the persistent “advice” is to Reset or reinstall Windows — a process that’s been shown, time and time again, to be ineffective. No, the Windows Update Troubleshooter doesn't work either."

    Jan 9, 2018 - "... It is important to note that OS-level and BIOS (microcode) patches that are designed to mitigate Meltdown and Spectre may lead to performance issues. It is important to test all patches before deploying.
    Some of these updates are incompatible with third-party antivirus software, and may require updating AV on workstations and servers. Microsoft has released guidance documents for both Windows clients and servers. Windows Server requires registry changes in order to implement the protections added by the patches.
    Microsoft has also halted the deployment of patches for some AMD systems, as there have been issues with systems after installation.
    Aside from these patches, today Microsoft has released patches covering 59 vulnerabilities. Of these vulnerabilities, 16 are ranked as “Critical,” with 20 potentially leading to remote code execution.
    In today’s release there are patches for both Microsoft Word and Outlook, which should also be prioritized for workstation-type devices. Most of the patches released today are for browsers and involve the Scripting Engine. These patches should be prioritized for systems that access the internet via a browser..."

    Exclamation BIOS Updates to Patch CPU Flaws

    FYI...

    BIOS Updates to Patch CPU Flaws
    - http://www.securityweek.com/device-m...atch-cpu-flaws
    Jan 15, 2018 - "Acer, Asus, Dell, Fujitsu, HP, IBM, Lenovo, Panasonic, Toshiba and other device manufacturers have started releasing BIOS updates that should patch the recently disclosed Spectre and Meltdown vulnerabilities.
    The flaws exploited by the Meltdown and Spectre attacks, tracked as CVE-2017-5715, CVE-2017-5753and CVE-2017-5754, allow malicious applications to bypass memory isolation mechanisms and access sensitive data. Billions of PCs, servers, smartphones and tablets using processors from Intel, AMD, ARM, IBM and Qualcomm are affected...

    "CPU Patches - (January 9, 10, & 11, 2018)
    Some vendor patches for the Spectre and Meltdown CPU vulnerabilities have been causing problems for users. Microsoft said that systems running incompatible anti-virus products would not receive any further updates; anti-virus vendors must confirm compatibility by setting a registry key. Linux has released microcode to address the CPU problems for certain processors. Canonical had to release a new patch after Ubuntu Xenial 16.04 users reported that the first fix rendered their systems unable to boot. Google says it applied patches for the flaws last year and that they have not slowed down its cloud services.
    The patches are complicated and some require steps beyond just clicking install to complete the mitigation. They are also changing rapidly as issues surface and are resolved. Test not only for stability after application but also for performance impact.
    There are patches and then there are PATCHES. It is pretty clear that software/firmware PATCHES for Spectre/Meltdown are complex and will, at a minimum, have performance impact. They will require significantly more QA testing than routine monthly Microsoft vulnerability Tuesday patches, probably even more than quarterly Oracle CPU PATCHES. Spinning up production environments (with obfuscated data) on IaaS services has enabled many organizations to increase depth of patch/PATCH testing while minimizing increases in time to patch. But, shielding, mitigation and monitoring will be needed in the interim..."

    Exclamation GRC test utility for 'Meltdown and Spectre', Tracking Issues with the Spectre Patches

    FYI...

    GRC test utility for 'Meltdown and Spectre' vulnerabilties
    - https://www.grc.com/inspectre.htm
    Jan 15, 2018 - "This is the Initial Release of InSpectre - We did not wish to delay this application's release while building additional confidence in its conclusions and output. It has been carefully tested under as many different scenarios as possible. But new is new, and it is new. We may well have missed something. So please use and enjoy InSpectre now. But you may wish to check back in a few days to see whether we may have found and fixed some last bits of debris.... Protection from these two significant vulnerabilities requires updates to every system's hardware – its BIOS which reloads updated processor firmware – and its operating system – to use the new processor features. To further complicate matters, newer processors contain features to minimize the performance impact of these important security improvements. But older processors, lacking these newer features, will be significantly burdened and system performance will suffer under some workloads.
    This InSpectre utility was designed to clarify every system's current situation so that appropriate measures can be taken to update the system's hardware and software for maximum security and performance."
    (Download the utility from the URL above.) - Thank you, Steve!!!

    ... Added Jan 16, 2018: "High incidence of -false-positive- A/V warnings:
    People are reporting that their 3rd-party anti-virus systems are quarantining InSpectre under the mistaken belief that it's malicious. This did not occur during early work, and is almost certainly due to the end-of-project inclusion of the protection enable/disable buttons and the presence of the registry key they use. I would rather not remove that feature... I will explore obscuring the use of that key to see whether false positive anti-virus warnings can be eliminated. At that time I will clarify some of the conflicting language the app can produce and also explain why the enable/disable buttons may be disabled (there's nothing for them to enable or disable in specific circumstances.)"

    Patch Watch: Tracking Issues with the Spectre Patches on AMD Machines
    > https://windowssecrets.com/windows-s...-amd-machines/
    Jan 11, 2018 - "Beware, AMD chip owners. For you Windows Secrets readers who have computers with AMD inside, these Spectre/Meltdown patches are causing more issues than they are preventing. So much so that Microsoft has halted release of the updates on machines that have AMD chipsets. Some of the relevant security posts include the following:
    Microsoft’s KB4073707 on the issues with AMD chip sets and how Microsoft is blocking the patches until the issue is resolved:
    - https://support.microsoft.com/en-us/...-based-devices
    Microsoft’s KB4073757 recapping the overall guidance:
    - https://support.microsoft.com/en-us/...ectre-meltdown
    Let’s recap the big picture:
    > Intel CPU chips have a bug in their very architecture.
    Researchers found a way for attackers to possibly steal passwords and other confidential information from our machines. As of publication, the attack has not been used in the wild. However, the potential is there and it’sreally concerning up in cloud servers as it could mean that fellow virtual servers could read information from a tenant next door.
    It won’t be enough to patch for the Windows operating system, you’ll need to patch the firmware on your computer as well.
    It’s not a Microsoft bug, but because everything uses CPUs, pretty much everything needs to be patched ranging from phones to firewalls. So after you get your patches for Windows, go look for updates for anything else that has a CPU included in it (I’m not kidding or overstating the issue).
    A bigger concern to many will be the performance hit this “fix” will make on your system as discussed in a Microsoft blog[2].
    2] https://cloudblogs.microsoft.com/mic...ndows-systems/
    The older your computer the more the “hit” will be. If you have a computer that is a 2015-era PC with Haswell or older CPU – you will notice a difference.
    CERT goes so far as to recommend replacing the CPU hardware in their blog post[1]. I’m not ready to go that far, but it would be wise to review how old your computer hardware is, evaluate the performance hit and plan accordingly.
    1] https://web.archive.org/web/20180104...vuls/id/584653
    Check That Your Antivirus Is Supported:
    Because this is a kernel update, antivirus vendors who have hooked into the kernel for additional protection could trigger blue screens of death if they are not updated for the change introduced by this patch. Thus Microsoft is requiring that before the January Windows and .NET updates are installed that a registry entry is made by the vendor – or by you if your vendor doesn’t provide the registry key in an update – before the January updates are installed.
    Make sure you review the antivirus listing page that is tracking all of the antivirus vendors and when they plan to support these January updates. If your vendor doesn’t support these updates, it’s time to find a new vendor...
