Use-after-free vulnerability in the browser engine in Mozilla Firefox before 3.6.28 and 4.x through 10.0, Firefox ESR 10.x before 10.0.3, Thunderbird before 3.1.20 and 5.0 through 10.0, Thunderbird ESR 10.x before 10.0.3, and SeaMonkey before 2.8 allows remote attackers to execute arbitrary code via vectors involving an empty argument to the array.join function in conjunction with the triggering of garbage collection.

Security readout for executives and security teams

This is an old Mozilla browser-engine memory safety flaw that could let a remote attacker run code in affected Firefox, Thunderbird, or SeaMonkey versions. The provided record names fixed version thresholds, but gives no CVSS score. Business urgency is high only where legacy Mozilla software remains installed. Exposure is most likely on unmanaged, legacy, kiosk, lab, or embedded endpoints still running the listed Mozilla versions. Current Mozilla installations are not shown as affected by the provided version ranges. Medium for most modern environments, high where old Mozilla software still exists. The issue enables remote code execution, but the affected versions are from 2012 and the bundle does not show current active exploitation. Mitigation focus: Upgrade Firefox, Firefox ESR, Thunderbird, Thunderbird ESR, and SeaMonkey beyond the fixed versions listed in the CVE.; Remove unsupported Mozilla builds from endpoints where upgrade is not possible.; Check operating-system vendor advisories for packaged browser and mail client updates..
