Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR
102.13, Thunderbird 115.0, and Thunderbird 102.13. 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 < 116, Firefox ESR < 102.14, and Firefox ESR
< 115.1.
