Mozilla Firefox ESR and 1 other: Out-of-bounds Write
CVE-2022-22752 is fixed in 4 products on 2 platforms, first by firefox 96.0+build2-0ubuntu0.18.04.1, released January 12, 2022. It is not reported as exploited. Patch Radar priority: High.
Mozilla developers Christian Holler and Jason Kratzer reported memory safety bugs present in Firefox 95. 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 < 96.
