CVE-2022-46874 Information

Description

A file with a long filename could have had its filename truncated to remove the valid extension leaving a malicious extension in its place. This could potentially led to user confusion and the execution of malicious code.
Note: This issue was originally included in the advisories for Thunderbird 102.6 but a patch (specific to Thunderbird) was omitted resulting in it actually being fixed in Thunderbird 102.6.1. This vulnerability affects Firefox < 108 Thunderbird < 102.6.1 Thunderbird < 102.6 and Firefox ESR < 102.6.
