Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:8 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.
