Security Updates for Windows Defender (December 2023)

high Nessus Plugin ID 186903


An antimalware application installed on the remote host is affected by a denial of service vulnerability.


The Malware Protection Engine version of Microsoft Windows Defender installed on the remote Windows host is prior to 4.18.23110.3. It is, therefore, affected by a denial of service vulnerability. An attacker can exploit this issue to cause the affected component to deny system or application services.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Update Microsoft Defender version 4.18.23110.3 to address this issue.
