Security researchers Tyson Smith and Jesse Schwartzentruber of the BlackBerry Security Automated Analysis Team used the Address Sanitizer tool while fuzzing to discover a use-after-free in the event listener manager. This can be triggered by web content and leads to a potentially exploitable crash. This issue was introduced in Firefox 29 and does not affect earlier versions.
