Mozilla developers and community members Tyson Smith and Christian Holler
reported memory safety bugs present in Firefox 74 and Firefox ESR 68.6.
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 < 68.7.0, Firefox ESR < 68.7,
and Firefox < 75.
