New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host is vulnerable to a buffer overflow.


The remote host is running Windows Live Messenger.

This version of Windows Live Messenger is vulnerable to a flaw in the way that it processes video messages. An attacker exploiting this flaw would need to be able to initiate a chat session with a user running a vulnerable version of the software. Successful exploitation would result in the attacker executing arbitrary code.


Upgrade to version 8.1.0178 or higher.
