Gentoo Linux Security Advisory 202208-14 - Multiple vulnerabilities have been found in Mozilla Thunderbird, the worst of which could result in the arbitrary execution of code. Versions less than 91.12.0 are affected.
Mozilla developers reported memory safety bugs present in Firefox 91 and Firefox ESR 78.13. 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 ESR < 78.14, Thunderbird < 78.14, and Firefox < 92.
