The JavaScript engine in Mozilla Firefox 3.x before 3.0.9, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.16 allows remote attackers to cause a denial of service (application crash) and possibly trigger memory corruption via vectors involving (1) js_FindPropertyHelper, related to the definitions of Math and Date; and (2) js_CheckRedeclaration.

Security readout for executives and security teams

This is an old Mozilla JavaScript engine flaw affecting Firefox, Thunderbird, and SeaMonkey versions from 2009 and earlier. A remote attacker could make the application crash and may be able to trigger memory corruption. Business risk is mainly from forgotten legacy desktops, servers, or embedded systems still running these obsolete packages. Exposure is likely limited to legacy Mozilla installations or old Linux distribution packages that were never updated. Current mainstream deployments should not be affected unless they retain obsolete Firefox, Thunderbird, SeaMonkey, or bundled Mozilla engine components. Treat this as a legacy-risk cleanup item unless affected software is still in use. Any confirmed deployment should be updated or retired promptly because browser and mail-client memory corruption issues can carry outsized risk despite the missing CVSS score. Mitigation focus: Upgrade Firefox, Thunderbird, and SeaMonkey beyond the fixed versions listed in the CVE.; Apply relevant OS vendor security updates for packaged Mozilla components.; Retire unsupported systems that cannot receive Mozilla or distribution security updates..
