Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the
Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird
102.5. 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 Firefox < 108, Firefox ESR <
102.6, and Thunderbird < 102.6.
