Memory safety bugs present in Firefox 116, Firefox ESR 102.14, Firefox ESR
115.1, Thunderbird 102.14, 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 < 102.15, Firefox ESR <
115.2, Thunderbird < 102.15, and Thunderbird < 115.2.
