Note: Versions mentioned in the description apply only to the upstream thunderbird package and not the thunderbird package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

Mozilla developers and community members reported memory safety bugs present in Firefox 93 and Firefox ESR 91.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
