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.

Synopsis

The remote host has a web browser installed that is vulnerable by a user-after-free vulnerability

Description

Versions of SeaMonkey 2.16.x earlier than 2.16.1 are potentially affected.

An error exists in the HTML editor (nsHTMLEditor) related to content script and the calling of the function 'document.execCommand' while internal editor operations are running. The previously freed memory can be dereferenced and could lead to arbitrary code execution

Solution

Upgrade to SeaMonkey 2.16.1 or later.
