Mozilla Firefox, Thunderbird, and Seamonkey are prone to a memory-corruption vulnerability because they fail to adequately validate user-supplied data.

Successful exploits may allow an attacker to execute arbitrary code in the context of the user running an affected application. Failed exploit attempts will result in a denial-of-service condition.

This issue affects versions prior to:

Firefox 3.6.11
Firefox 3.5.14
Thunderbird 3.1.5
Thunderbird 3.0.9
SeaMonkey 2.0.9
