Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Security readout for executives and security teams

This 2012 Mozilla issue affected old Firefox, Thunderbird, and SeaMonkey versions. A remote attacker could crash the application and might execute arbitrary code through unspecified vectors. The main business concern is any remaining legacy desktop or server image still running these end-of-life builds. Exposure is most likely in legacy systems, archived virtual desktops, unmanaged endpoints, old Linux distributions, or appliances bundling outdated Mozilla components. Modern supported Mozilla releases are outside the listed affected ranges. Treat this as a legacy-software eradication issue. It is high priority where affected clients remain in use, because browser-engine memory corruption can cross from user browsing or email activity into code execution risk. Mitigation focus: Upgrade Firefox, Thunderbird, and SeaMonkey beyond the listed fixed versions.; Apply relevant Debian, SUSE, Mandriva, or vendor package updates where applicable.; Retire unsupported browser and mail-client builds from managed images..
