Mozilla Firefox ESR and 2 others: Out-of-bounds Write
CVE-2022-28288 is fixed in 5 products on 2 platforms, first by Mozilla Firefox (en-US) 99.0, released April 5, 2022. It is not reported as exploited. Patch Radar priority: High.
Mozilla developers and community members Randell Jesup, Sebastian Hengst, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 98. 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 < 99.
