Patch Tuesday, December 2019

December's Patch Tuesday is upon us, and, as in years gone by, it's a rather light month. All told there are 35 CVEs patched, including six rated "Critical," 28 rated as "Important," and one rated "Moderate." On the shortlist of patches rated "Critical" is one for a Remote Code Execution (RCE) for Windows Hyper-V and four separate RCE vulnerabilities in Git for Visual Studio. All developers using Visual Studio should prioritize patching before any holiday vacation. Git for Visual Studio also has tampering vulnerability rated "Moderate." An attacker who successfully exploited this vulnerability could write arbitrary files and directories to virtual drive paths on a vulnerable system. Attackers could utilize this to push malware or other malicious files to a victim.

The vulnerabilities rated as “Important” are a mixed bag of Remote Code Execution, Information Disclosure, and Elevation of Privilege vulnerabilities. They affect popular client software packages like Skype and the MS Office Suite (including an RCE vulnerability in Powerpoint) as well as the Windows operating system in general.

Happy holidays and stay safe this season!
