This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Firefox. User interaction is required to
exploit this vulnerability in that the target must visit a malicious
page or open a malicious file.
The specific flaw exists within js3250.dll. In the JSON.stringify() call
