If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way Thunderbird repeatedly attempts to process and display the message, which could cause Thunderbird's user interface to lock up and no longer respond to the user's actions. An attacker could send a crafted message with this structure to attempt a DoS attack. External Reference: https://www.mozilla.org/en-US/security/advisories/mfsa2023-07/#CVE-2023-0616
