The NativeKey widget in Mozilla Firefox before 24.0, Thunderbird before 24.0, and SeaMonkey before 2.21 processes key messages after destruction by a dispatched event listener, which allows remote attackers to cause a denial of service (application crash) by leveraging incorrect event usage after widget-memory reallocation.
