CVE-2013-0746: n/a vulnerability

CVE-2013-0746: Mozilla Firefox before 18.0, Firefox ESR 10.x before 10.0.12 and 17.x before 17.0.2, Thunderbird before 17....

Mozilla Firefox before 18.0, Firefox ESR 10.x before 10.0.12 and 17.x before 17.0.2, Thunderbird before 17.0.2, Thunderbird ESR 10.x before 10.0.12 and 17.x before 17.0.2, and SeaMonkey before 2.15 do not properly implement quickstubs that use the jsval data type for their return values, which allows remote attackers to execute arbitrary code or cause a denial of service (compartment mismatch and application crash) via crafted JavaScript code that is not properly handled during garbage collection.

Security readout for executives and security teams

This is an old Mozilla browser and mail-client memory handling flaw. A malicious page or JavaScript-bearing content could crash the application or potentially run code on systems still using vulnerable Firefox, Thunderbird, or SeaMonkey versions. Exposure is mainly legacy systems running Firefox before 18.0, Firefox ESR before 10.0.12 or 17.0.2, Thunderbird before 17.0.2, matching Thunderbird ESR releases, or SeaMonkey before 2.15. Prioritize remediation where legacy Mozilla applications remain in use, especially on endpoints handling untrusted web or email content. Modern supported installations should already be beyond the affected versions. Mitigation focus: Upgrade affected Mozilla applications to the fixed versions or later.; Apply relevant Red Hat, Ubuntu, SUSE, or openSUSE security updates.; Retire unsupported legacy browser and mail-client versions..
