Use-after-free vulnerability in Mozilla Firefox before 16.0, Firefox ESR 10.x before 10.0.8, Thunderbird before 16.0, Thunderbird ESR 10.x before 10.0.8, and SeaMonkey before 2.13 might allow user-assisted remote attackers to execute arbitrary code via vectors involving use of mozRequestFullScreen to enter full-screen mode, and use of the history.back method for backwards history navigation.

Security readout for executives and security teams

This is an old Mozilla browser and mail-client memory safety flaw. A malicious page could potentially cause code execution after user interaction with full-screen and navigation behavior. The main business risk is unmanaged legacy Firefox, Thunderbird, SeaMonkey, or Linux-packaged Mozilla builds that were never updated. Exposure is likely limited to obsolete Mozilla products or long-retired enterprise images. The supplied CVE record lacks CPE detail, so version inventory is required rather than relying on automated product matching alone. Prioritize this if legacy desktop software exists in production, VDI, jump hosts, or archived gold images. For fully modernized fleets, urgency is mostly audit and cleanup rather than emergency response. Mitigation focus: Upgrade affected Mozilla products to fixed or later versions.; For Linux packages, apply the relevant vendor security update.; Remove unsupported Firefox, Thunderbird, and SeaMonkey installations..
