When importing a revoked key that specified key compromise as the revocation reason, Thunderbird did not update the existing copy of the key that was not yet revoked, and the existing key was kept as non-revoked. Revocation statements that used another revocation reason, or that didnt specify a revocation reason, were unaffected. This vulnerability affects Thunderbird < 91.8.
The product does not validate, or incorrectly validates, a certificate.
