Mozilla developers Ashley Hale and the Mozilla Fuzzing Team reported memory
safety bugs present in Firefox 105 and Firefox ESR 102.3. 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 < 106, Firefox ESR < 102.4, and Thunderbird <
102.4.
