CVE-2023-50761

Name of the Vulnerable Software and Affected Versions Thunderbird versions prior to 115.6

Description The issue is related to the implementation of the S/MIME standard in the Thunderbird email client, specifically with errors in checking the cryptographic signature due to a mismatch in the date and time of its creation. This could allow a remote attacker to impact the confidentiality, integrity, and availability of protected information by giving recipients the impression that a message was sent at a different date or time.

Recommendations For versions prior to 115.6, update to version 115.6 or later to resolve the issue. At the moment, there is no information about additional mitigation measures for this vulnerability.
