## Microsoft starts off new year with relatively light Patch Tuesday, no zero-days
Microsoft followed up one of the lightest recent Patch Tuesdays in December with another month of no zero-day vulnerabilities and only two critical issues.

The company started out 2024 by disclosing 48 vulnerabilities on Tuesday across its suite of products and services, 46 of which are considered of “important” severity.
One of the critical vulnerabilities patched Tuesday is CVE-2024-20674 , a security bypass vulnerability in the Windows Kerberos authentication protocol. An attacker could carry out a man-in-the-middle at
