This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla 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 the way Firefox handles nsDOMAttribute child removal. It is possible to remove a child without setting the removed child pointer to NULL, thus leaving it still accessible as a dangling pointer. Subsequent use of this pointer allows for remote code execution.
