Mozilla developers Andrew McCreight, Gabriele Svelto, Tom Ritter and the
Mozilla Fuzzing Team reported memory safety bugs present in Firefox 99 and
Firefox ESR 91.8. 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 Thunderbird <
91.9, Firefox ESR < 91.9, and Firefox < 100.
