Use-after-free vulnerability in the mozilla::TrackUnionStream::EndTrack implementation in Mozilla Firefox before 18.0, Firefox ESR 17.x before 17.0.1, Thunderbird before 17.0.2, Thunderbird ESR 17.x before 17.0.1, and SeaMonkey before 2.15 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.

Security readout for executives and security teams

This is an old Mozilla memory-safety flaw that could let a remote attacker crash affected applications or potentially run code. The source bundle names Firefox, Firefox ESR, Thunderbird, Thunderbird ESR, and SeaMonkey versions from before January 2013 fixes. There is no KEV listing or active exploitation evidence in the provided sources. Exposure is most likely on legacy endpoints, embedded systems, lab machines, or archived server images still running obsolete Mozilla browser or mail client builds. Modern supported releases should not be affected if patched beyond the named fixed versions. Prioritize remediation where obsolete Mozilla applications remain on business systems. The bug has remote code execution potential, but the main business risk today is unmanaged legacy software rather than a documented current campaign. Mitigation focus: Update Firefox to 18.0 or later, or a current supported release.; Update Firefox ESR 17.x to 17.0.1 or later.; Update Thunderbird to 17.0.2 or later..
