Microsoft’s December Patch Tuesday updated delivers 59 fixes, including two zero-days (CVE-2022-44698 and CVE-2022-44710) that require immediate attention on the Windows platform. This is a network focused update (TCP/IP and RDP) that will require significant testing with an emphasis on ODBC connections, Hyper-V systems, Kerberos authentication, and printing (both local and remote).
Microsoft also published an urgent out-of-band update (CVE-2022-37966) to address serious Kerberos authentication issues. (The team at Readiness has provided a helpful infographic that outlines the risks associated with each of these updates.)
