Patch Tuesday December edition brings an important security update for Windows 7. Update KB3205394 offers six major security fixes, patching severe vulnerabilities that could allow remote code execution.

Windows 7 KB3205394 doesn’t include any new operating system features, focusing only on security updates. More specifically, the update patches a series of vulnerabilities affecting the common log file system driver, Windows 7 OS, kernel-mode drivers, and more.

Security update KB3205394 patches

  1. MS16-153 common log file system driver vulnerabilities
    These vulnerabilities could allow information disclosure when the Windows Common Log File System driver improperly handles objects in memory.
  2. MS16-151 Windows kernel-mode driver vulnerability
    More exactly, this vulnerability could allow elevation of privilege, meaning that attackers could then easily take control of the affected system.
  3. MS16-149 Microsoft Windows vulnerability
    Just like the second vulnerability on the list, this OS weakness could allow elevation of privilege.
  4. MS16-147 Microsoft Uniscribe vulnerability
    This flaw could allow remote code execution.
  5. MS16-146 Microsoft graphics component vulnerabilities
    Again, most severe of these flaws could allow remote code execution.
  6. MS16-144 Internet Explorer vulnerabilities

To benefit from the latest Windows 7 security patches, you can either install only the security update KB3205394, or the Windows 7 Monthly Rollup KB3207752. The only difference is that the Monthly Rollup also includes improvements and fixes from previous monthly rollups.

How to install KB3205394

You can install KB3205394 only via the Microsoft Update Catalog website. The stand alone KB3205394 package is not available through Windows Update.
