Patch Tuesday, February 2021

February is here and with it comes a relatively light Patch Tuesday. Only 56 CVEs are being patched today. That includes eleven rated as "Critical", 42 rated as "Important", and three rated "Moderate". On the list of vulnerabilities rated as "Critical", you'll find vulnerabilities in .NET, various media codecs, Windows DNS and Fax services, and two in the Windows TCP/IP stack.

The list of "Important" CVEs includes Remote Code Execution vulnerabilities in MS Excel, Sharepoint, and Visual Studio as well as dozens of Privilege Escalation and Denial of Service vulnerabilities. All told, seven of these vulnerabilities have been exploited in the wild as a zero-day in very targeted attacks. This includes a Remote Code Execution vulnerability in .NET Core/Visual Studio. This makes this patch cycle even more crucial than ever.

Patch as early as you can and please stay safe!
