CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 0CVE-2022-31747 – Mozilla: Memory safety bugs fixed in Firefox 101 and Firefox ESR 91.10
https://notcve.org/view.php?id=CVE-2022-31747
Mozilla developers Andrew McCreight, Nicolas B. Pierron, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 100 and Firefox ESR 91.9. 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 Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
