{"id":"CVE-2023-50761","details":"The signature of a digitally signed S/MIME email message may optionally specify the signature creation date and time. If present, Thunderbird did not compare the signature creation date with the message date and time, and displayed a valid signature despite a date or time mismatch. This could be used to give recipients the impression that a message was sent at a different date or time. This vulnerability affects Thunderbird \u003c 115.6.","modified":"2026-04-16T00:05:48.399421580Z","published":"2023-12-19T14:15:07.033Z","related":["ALSA-2024:0001","ALSA-2024:0003","SUSE-SU-2024:0044-1","openSUSE-SU-2024:13519-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/12/msg00021.html"},{"type":"ADVISORY","url":"https://www.debian.org/security/2023/dsa-5582"},{"type":"ADVISORY","url":"https://www.mozilla.org/security/advisories/mfsa2023-55/"},{"type":"REPORT","url":"https://bugzilla.mozilla.org/show_bug.cgi?id=1865647"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-50761.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"115.6"}]},{"events":[{"introduced":"0"},{"last_affected":"11.0"}]},{"events":[{"introduced":"0"},{"last_affected":"12.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N"}]}
