Vulnerability details

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of user-supplied data when processing signed and encrypted attached messages. If an email contains 2 attached messages, Thunderbird displays security status of the first opened attached message for the second attached message. As a result an attacker can spoof security status of the second attached message.
