Certain crafted MIME email messages that claimed to contain an encrypted OpenPGP message, which instead contained an OpenPGP signed message, were wrongly shown as being encrypted. This vulnerability affects Thunderbird < 136 and Thunderbird < 128.8.

Multiple vulnerabilities have been discovered in Mozilla Thunderbird, the worst of which could lead to remote code execution. Versions greater than or equal to 128.9.0 are affected.
