Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 27.0 and SeaMonkey before 2.24 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the MPostWriteBarrier class in js/src/jit/MIR.h and stack alignment in js/src/jit/AsmJS.cpp in OdinMonkey, and unknown other vectors.

Security readout for executives and security teams

This is an old Mozilla browser-engine issue affecting Firefox before 27.0 and SeaMonkey before 2.24. A malicious remote input could crash the browser and may allow arbitrary code execution. Business urgency is mainly for legacy systems that still run these obsolete versions. Exposure is likely limited to unmanaged, embedded, kiosk, lab, or legacy desktop environments still running Firefox before 27.0 or SeaMonkey before 2.24. Current supported browser versions are not indicated as affected by the provided sources. Treat this as a legacy hygiene issue with high impact if present. It should not distract from current exploited vulnerabilities unless vulnerable old browsers still exist in the environment. Mitigation focus: Upgrade Firefox to 27.0 or later and SeaMonkey to 2.24 or later.; Remove obsolete Mozilla browser versions from managed endpoints and base images.; Check OS vendor advisories for patched distro browser packages..
