CVE-2022-1197
CVSS v3.1
8.8
High
| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Thunderbird versions prior to 91.8
Description
The issue is related to errors when updating the OpenPGP digital signature, which can allow a remote attacker to perform a spoofing attack. Specifically, when importing a revoked key that specified key compromise as the revocation reason, Thunderbird did not update the existing copy of the key, keeping it as non-revoked.
Recommendations
For versions prior to 91.8, update to version 91.8 or later to resolve the issue. As a temporary workaround, consider restricting the use of OpenPGP digital signatures until a patch is available. Avoid importing revoked keys that specify key compromise as the revocation reason in the affected versions.
