CVE-2021-23992 log

Severity Medium
Remote Yes
Type Signature forgery
Thunderbird before version 78.9.1 did not check if the user ID associated with an OpenPGP key has a valid self signature. An attacker may create a crafted version of an OpenPGP key, by either replacing the original user ID, or by adding another user ID. If Thunderbird imports and accepts the crafted key, the Thunderbird user may falsely conclude that the false user ID belongs to the correspondent.
