Multiple memory corruption flaws exist in multiple Mozilla products. The program fails to sanitize user-supplied input resulting in memory corruption. This may allow a remote attacker to execute arbitrary code.

Upgrade Firefox and Thunderbird to version 12.0 or higher (10.0.4 for ESR) and SeaMonkey to version 2.9 or higher, as they have been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
