Mozilla Firefox/Thunderbird JavaScript Engine Memory Corruption Vulnerabilities

Mozilla Firefox and Thunderbird are prone to multiple remote memory-corruption vulnerabilities that affect the JavaScript engine.

An attacker can exploit these issues to corrupt memory on the affected computer and run arbitrary code in the context of the user running the affected application. Failed exploit attempts will cause denial-of-service conditions.

These vulnerabilities were previously covered in BID 35758 (Mozilla Firefox MFSA 2009-34, -35, -36, -37, -39, -40 Multiple Vulnerabilities) but have been assigned this record to better document them.
