Synopsis
The remote Mac OS X host contains a mail client that is potentially affected by a use-after-free vulnerability.
Description
The installed version of Thunderbird 17.x 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 Thunderbird 17.0.4 or later.
