Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 13.0, Thunderbird before 13.0, and SeaMonkey before 2.10 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) methodjit/ImmutableSync.cpp, (2) the JSObject::makeDenseArraySlow function in js/src/jsarray.cpp, and unknown other components.

Security readout for executives and security teams

This is an old Mozilla browser-engine memory corruption issue. Affected Firefox, Thunderbird, and SeaMonkey versions could crash, and Mozilla indicated arbitrary code execution was possible. Business risk is mainly from legacy systems still running pre-2012 builds. Exposure is likely limited to unmanaged or legacy endpoints, old Linux distribution packages, embedded images, or forensic lab systems retaining Firefox before 13.0, Thunderbird before 13.0, or SeaMonkey before 2.10. Treat as a legacy exposure cleanup item with high impact if found. It is not currently KEV-listed in the supplied evidence, but affected versions are far beyond support and should not remain in production. Mitigation focus: Upgrade Firefox and Thunderbird to 13.0 or later.; Upgrade SeaMonkey to 2.10 or later.; Apply supported vendor distribution updates where Mozilla packages are OS-managed..
