Currently, no other vendors have identified patches that are scheduled to be released on November 11. This content will be updated as additional information is made available.
Update November 13 10 a.m.
As expected the patches released on Tuesday, November 11 were extensive. As previously indicated, there were a total of sixteen patches scheduled to be released by Microsoft. However, only fourteen are available as of November 13. The patches are designated Bulletin IDs MS14-064 through MS14-079. Bulletins identified as MS14-068 and MS14-075 have been revised to have release dates that are to be determined.
Based on the severity of vulnerabilities identified in bulletins https://technet.microsoft.com/library/security/MS14-064 (which applies to Object Linking and Embedding and is designated as CRITICAL even for server operating systems) and https://technet.microsoft.com/library/security/MS14-065 (which addresses seventeen privately reported vulnerabilities in Internet Explorer), it is recommended that the patches be applied to both server and workstation operating systems as soon as possible.
Additionally, a CRITICAL vulnerability has been identified for operating systems that use TLS (also known as schannel) for secure communication; commonly used for Https connections to web or email servers. The bulletin for the schannel patch is identified as https://technet.microsoft.com/library/security/MS14-066 is particularly significant as it could allow remote code execution if an attacker sends a specially crafted packets to a windows server. This patch should also be applied (especially to server systems) as soon as possible.
Adobe also issued an update for Flash on November 11. The new version of flash for all browsers should be 126.96.36.199. For browsers other than Google Chrome and Internet Explorer 10/11, the updated version should be downloaded from Adobe.

According to Microsoft, the vulnerability is an elevation of privilege exploit and had not been disclosed publicly prior to November 18. However, other resources – (such as https://nakedsecurity.sophos.com/2014/11/19/microsoft-tops-up-patch-tuesday-issues-delayed-fix-for-zero-day-hole-in-logon-security/ ) indicate the vulnerability had been identified publicly previously. The vulnerability could allow an user with an authorized domain logon ID to elevate the privilege to that of a domain administrator. Most resources are recommending that the patch be applied to all Windows server operating systems as soon as possible.
