Microsoft's January 2024 Patch Tuesday features updates addressing 49 security flaws across their software range, including two critical vulnerabilities in Windows Kerberos and Hyper-V RCE.
The update comprehensively covers various security concerns categorized into remote code execution, elevation of privilege, security feature bypass, information disclosure, denial of service, and spoofing vulnerabilities.
It resolves an Office vulnerability (CVE-2024-20677) related to embedded FBX 3D model files in documents and a critical Kerberos bug (CVE-2024-20674) that allowed bypassing authentication.
Microsoft isn't reporting any active exploitation of these issues, but patching is still a wise choice.
