Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1. 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 < 93, Thunderbird < 91.2, and Firefox ESR < 91.2.

Affected Software

Name Vendor Start Version End Version
Firefox Mozilla * 93.0 (excluding)
Firefox_esr Mozilla * 91.2 (excluding)
