Firefox ESR 17.x < 17.0.4 nsHTMLEditor Use-After-Free

high Nessus Plugin ID 65130

Language:

Synopsis

The remote Windows host contains a web browser that is potentially affected by a use-after-free vulnerability.

Description

The installed version of Firefox ESR 17.x is earlier than 17.0.4, and thus, is potentially affected by a use-after-free vulnerability.

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 Firefox 17.0.4 ESR or later.
