Mozilla Thunderbird and 1 other: When processing a PGP/MIME payload that contains digitally signed text, the first paragraph of the text…
CVE-2023-50762 is fixed in 7 products on 2 platforms, first by DEBIAN-CVE-2023-50762, released December 19, 2023. It is not reported as exploited. Patch Radar priority: High.
When processing a PGP/MIME payload that contains digitally signed text, the first paragraph of the text was never shown to the user. This is because the text was interpreted as a MIME message and the first paragraph was always treated as an email header section. A digitally signed text from a different context, such as a signed GIT commit, could be used to spoof an email message. This vulnerability affects Thunderbird < 115.6.
