Unspecified vulnerability in the browser engine in Mozilla Firefox 3.5.x before 3.5.19 and 3.6.x before 3.6.17, Thunderbird before 3.1.10, and SeaMonkey before 2.0.14 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors, a different vulnerability than CVE-2011-0072, CVE-2011-0074, CVE-2011-0075, and CVE-2011-0077.

Security readout for executives and security teams

CVE-2011-0078 is an old Mozilla browser-engine memory corruption issue. A malicious remote source could crash affected applications and might execute code. The public record names Firefox, Thunderbird, and SeaMonkey versions from 2011; modern fully updated deployments are unlikely to be exposed. Exposure is mainly legacy endpoints, old packaged browsers or mail clients, and unsupported systems still running the named Mozilla versions. The provided affected-product metadata is incomplete, so inventory validation is necessary. Treat this as high priority only where legacy affected software remains. It is not a broad modern-platform emergency based on the provided evidence, but any confirmed exposure should be removed because possible code execution is listed. Mitigation focus: Upgrade Firefox, Thunderbird, and SeaMonkey beyond the affected versions.; Remove unsupported Mozilla 3.x-era applications from managed endpoints.; Check Debian, Mandriva, Mozilla, Oracle, and Avaya advisories for environment-specific guidance..
