Mozilla developers Andrew McCreight and Gabriele Svelto reported memory
safety bugs present in Thunderbird 102.4. 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 < 102.5, Thunderbird < 102.5, and Firefox
< 107.
