Heap-based buffer overflow in the nsTextFrameUtils::TransformText function in Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 might allow remote attackers to execute arbitrary code via a bidirectional text run.

Security readout for executives and security teams

CVE-2010-3166 is an old Mozilla memory-corruption flaw affecting legacy Firefox, Thunderbird, and SeaMonkey releases. A crafted bidirectional text run could trigger a heap buffer overflow and may allow arbitrary code execution. Modern supported versions should not be affected by the listed vulnerable versions. Exposure is mainly organizations retaining very old Mozilla browser or mail-client versions, including embedded or vendor-bundled copies. Current managed endpoints are unlikely exposed if browsers and mail clients are supported and patched. Treat as high priority only if legacy Mozilla software remains in use. For modern environments, priority is confirmation and cleanup of unsupported software rather than emergency response. Mitigation focus: Upgrade Firefox, Thunderbird, and SeaMonkey beyond the fixed versions listed in the CVE record.; Remove unsupported legacy Mozilla products where upgrades are not feasible.; Check OS and vendor advisories for backported package fixes..
