Mozilla developers and community members reported memory safety bugs
present in Firefox 81 and Firefox ESR 78.3. 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 ESR < 78.4, Firefox < 82, and Thunderbird <
78.4.
