CVE-2012-4194: Mozilla Firefox before 16.0.2, Firefox ESR 10.x before 10.0.10, Thunderbird before 16.0.2, Thunderbird ESR...

Mozilla Firefox before 16.0.2, Firefox ESR 10.x before 10.0.10, Thunderbird before 16.0.2, Thunderbird ESR 10.x before 10.0.10, and SeaMonkey before 2.13.2 do not prevent use of the valueOf method to shadow the location object (aka window.location), which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via vectors involving a plugin.

Security readout for executives and security teams

This 2012 Mozilla issue affected old Firefox, Thunderbird, and SeaMonkey releases. A web or mail client could be made more susceptible to cross-site scripting through plugin-related behavior. Modern supported installations should not be exposed, but unmanaged legacy desktops or archived images may still carry risk. Exposure is most likely on legacy endpoints, old Linux distributions, VDI images, or unsupported systems still running the named Mozilla versions. Internet-facing servers are not the primary exposure described. Treat this as a legacy hygiene issue unless old Mozilla clients remain in production. Prioritize discovery and removal from managed endpoints, especially where users handle untrusted web or mail content. Mitigation focus: Upgrade affected Mozilla products to the fixed versions or later.; Apply relevant OS vendor updates from Ubuntu, Red Hat, or SUSE where applicable.; Retire unsupported Mozilla versions from managed endpoint images..
