The Chrome Object Wrapper (COW) and System Only Wrapper (SOW) implementations in Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 do not prevent modifications to a prototype, which allows remote attackers to obtain sensitive information from chrome objects or possibly execute arbitrary JavaScript code with chrome privileges via a crafted web site.

Security readout for executives and security teams

This is a browser-family privilege boundary flaw in older Mozilla products. A malicious website could potentially read privileged browser data or run JavaScript with chrome-level privileges. Modern systems are usually exposed only if they still run the listed legacy Firefox, Thunderbird, or SeaMonkey versions. Exposure is most likely in unmanaged legacy desktops, archived virtual machines, old Linux distributions, or systems pinned to obsolete Mozilla ESR packages. Current supported browser and mail clients should not be assumed affected without version evidence. Treat this as high priority only where legacy Mozilla software still exists. The potential privilege impact is serious, but the age of the issue means urgency depends on whether obsolete versions remain in the environment. Mitigation focus: Upgrade Firefox to 19.0 or later where applicable.; Upgrade Firefox ESR and Thunderbird ESR to 17.0.3 or later.; Upgrade Thunderbird to 17.0.3 or later..
