Mozilla developers reported memory safety bugs present in Firefox 83 and
Firefox ESR 78.5. 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 < 84,
Thunderbird < 78.6, and Firefox ESR < 78.6.
