Hello and welcome to this month’s blog on the Microsoft patch releases. This is another fairly heavy month, with 11 bulletins covering 20 vulnerabilities.
There are 10 critical issues this month affecting Internet Explorer, Excel, Active Directory, and the RPC service of Host Integration Server. All of them are remote code-execution issues, but the issues affecting Host Integration Server and Active Directory do not require any user interaction, making them potentially the worst of the bunch. The remaining issues (rated Important and Moderate) affect Message Queuing Service, Internet Printing Protocol (IPP), Windows Kernel, Ancillary Function Driver, Virtual Address Descriptors (VADs), and Server Message Block (SMB).
As always, customers are advised to follow these security best practices:
-Block external access at the network perimeter to specific sites and computers only.
-Avoid sites of questionable or unknown integrity.
-Never open files...
