CVE-2013-5613 is a critical use-after-free vulnerability in the PresShell::DispatchSynthMouseMove function affecting Mozilla Firefox, Firefox ESR, Thunderbird, and SeaMonkey. This flaw allows remote attackers to execute arbitrary code or cause a denial of service through heap memory corruption via crafted synthetic mouse movement.
