Mozilla developers Andrew McCreight, Nicolas B. Pierron, and the Mozilla
Fuzzing Team reported memory safety bugs present in Firefox 100 and Firefox
ESR 91.9. 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 < 91.10, Firefox
< 101, and Firefox ESR < 91.10.
