December's Patch Tuesday is here and, typical for the end of the year, it's a light month with only 58 CVEs patched. This includes 10 CVEs rated as "Critical", 46 rated as "Important" and 2 rated "Moderate". The short "Critical" list includes most of the month-to-month tenants including the Chakra Scripting Engine, Hyper-V, Dynamics 365, Exchange, Sharepoint, and Visual Studio. All of the "Critical" vulnerabilities are Remote Code Execution issues.
The "Important" list includes many of the same affected packages like Sharepoint and Dynamics, but you'll also want to make sure you're patching Azure. The core Windows OS is also affected through multiple packages like DirectX, Kerberos, SMB, Network connectivity, and Error logging. One vulnerability that affects NTFS file systems could allow an attacker with SMBv2 access to a vulnerable host to trigger arbitrary remote code. The last two bugs rated "Moderate"
Luckily none of this month's CVEs have any known public exploits, but make sure you get your systems patched before you check out for the year. And from each of us here at Trustwave SpiderLabs, have a wonderful holiday season and a happy New Year!
