Memory safety bugs present in Firefox 116, Firefox ESR 115.1, and
Thunderbird 115.1. 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 < 117,
Firefox ESR < 115.2, and Thunderbird < 115.2.
