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:11 relevant fixed versions and status.

A use-after-free vulnerability can occur while playing a sound notification in Thunderbird. The memory storing the sound data is immediately freed, although the sound is still being played asynchronously, leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 60.5.
