NVD Description

Note: Versions mentioned in the description apply only to the upstream thunderbird package and not the thunderbird package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

Concurrent use of the URL parser with non-UTF-8 data was not thread-safe. This could lead to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.
