Mozilla Thunderbird < 17.0.4 nsHTMLEditor Use-After-Free

This script is Copyright (C) 2013-2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

The installed version of Thunderbird 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.
