We strongly recommend patching all these latest security patches right away to avoid unnecessary security breaches, while installing the non-security patches at your discretion.

  • Microsoft Office Services and Web Apps

  • ASP.NET Core

Security advisories

Patch Tuesday for November 2017 includes two high priority security advisories, one for delivering updates to Flash, the other for delivering various security-related patches to Office Suite products.

High-priority security vulnerabilities

Microsoft Patch Tuesday for November 2017 contains two stand-alone security fixes that have to be patched immediately to avoid providing cyber criminals any loopholes:

  1. CVE-2017-11830 vulnerability in Windows Defender Device Guard allows attackers to bypass the application and execute commands remotely.
  2. CVE-2017-1187 vulnerability allows hackers to get past Microsoft Excel’s protection against macro execution.

Some quick advice: If you use Excel or Defender Device Guard on your network, it’s highly recommended to patch your computers right away. Both of these vulnerabilities pose a major threat to the security of your IT.

If your enterprise only has a limited number of Microsoft products that fall under this month’s Patch Tuesday updates, then you can filter your products and apply the security and non-security patches accordingly.

Just in time for Microsoft Patch Tuesday November, Adobe has also released a security update for Flash Player.
