Mozilla developers reported memory safety bugs present in Firefox and
Thunderbird 68.5. 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 Thunderbird <
68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
