December Patch Tuesday: Vulnerabilities in Windows components, RDP, and PowerPoint Get Fixes

Microsoft released a total of 36 patches for December’s Patch Tuesday. Decembers tend to have a relatively low number of patches, and the last Patch Tuesday of the 2010s was no different. Seven of the 36 patches were identified as Critical, 28 Important, and one Moderate. The vulnerabilities covered a wide variety of Microsoft products, including Windows, Internet Explorer, Office, Hyper-V Server, and SQL Server. None of the fixed vulnerabilities were disclosed to the public before patching, although one was under active attack at the time of the patch.
