The line-breaking implementation in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, Thunderbird before 3.0.11 and 3.1.x before 3.1.7, and SeaMonkey before 2.0.11 on Windows does not properly handle long strings, which allows remote attackers to execute arbitrary code via a crafted document.write call that triggers a buffer over-read.

Security readout for executives and security teams

This is an old Mozilla browser and mail-client memory handling flaw on Windows. A malicious webpage or HTML document could trigger a buffer over-read through long strings in line breaking and, per the CVE, allow arbitrary code execution. Affected versions are Firefox before 3.5.16/3.6.13, Thunderbird before 3.0.11/3.1.7, and SeaMonkey before 2.0.11. Exposure is most likely limited to legacy Windows systems still running the affected Mozilla versions or downstream Linux distribution packages from 2010-era releases. Modern supported Mozilla releases are not identified as affected in the supplied sources. Treat as high priority only if legacy affected software exists. The business risk is remote code execution through user-facing browsing or mail workflows, but the vulnerability is from 2010 and current exploitation evidence is not supplied. Mitigation focus: Upgrade Firefox, Thunderbird, and SeaMonkey beyond the fixed versions named in the CVE.; Remove unsupported Mozilla versions from managed Windows endpoints.; Check distribution advisories for fixed package versions where legacy Linux packages remain..
