CVE-2023-50762 Information

Description

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.
