Firefox ESR 17.x < 17.0.4 nsHTMLEditor Use-After-Free (Mac OS X)
High Nessus Plugin ID 65128
The remote Mac OS X host contains a web browser that is potentially affected by a use-after-free vulnerability.
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.
