Mozilla Firefox/Thunderbird/SeaMonkey CVE-2012-1973 Use-After-Free Memory Corruption Vulnerability
Mozilla Firefox, Thunderbird, and SeaMonkey are prone to a remote memory-corruption vulnerability due to a use-after-free condition.
A successful exploit will result in the execution of arbitrary attacker-supplied code in the context of the user running the affected application. Failed exploit attempts will likely result in denial-of-service conditions.
This issue is fixed in:
Firefox ESR 10.0.7
Thunderbird ESR 10.0.7
Note: This issue was previously discussed in BID 55249 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2012-57 through -72 Multiple Vulnerabilities) but has been moved to its own record to better document it.
