Jesse Ruderman and JW Wang discovered multiple memory safety issues in

message with scripting enabled, an attacker could potentially exploit
these to cause a denial of service via application crash, or execute
arbitrary code with the privileges of the user invoking Thunderbird.

Abhishek Arya discovered a use-after-free during DOM interactions with
