This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Mozilla Firefox. User interaction is

attacker controlled memory can be executed. Successful exploitation of
this vulnerability can lead to remote compromise of the affected system
under the credentials of the currently logged in user.
