Memory safety bugs present in Firefox 108 and Firefox ESR 102.6. 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 Firefox < 109, Thunderbird < 102.7, and
Firefox ESR < 102.7.
