CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 0CVE-2022-46878 – Mozilla: Memory safety bugs fixed in Firefox ESR 102.6 and Thunderbird 102.6
https://notcve.org/view.php?id=CVE-2022-46878
Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.5. 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 < 108, Firefox ESR < 102.6, and Thunderbird < 102.6. The Mozilla Foundation Security Advisory describes this flaw as: Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 107 and Firefox ESR 102.5.
