Mozilla Firefox ESR and 2 others: Out-of-bounds Write
CVE-2022-0511 is fixed in 5 products on 2 platforms, first by Mozilla Firefox (en-US) 97.0, released February 8, 2022. It is not reported as exploited. Patch Radar priority: High.
Mozilla developers and community members Gabriele Svelto, Sebastian Hengst, Randell Jesup, Luan Herrera, Lars T Hansen, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 96. 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 < 97.
