Mozilla Firefox and 2 others: Out-of-bounds Write
CVE-2022-46885 is fixed in 5 products on 2 platforms, first by Mozilla Firefox (en-US) 106.0, released October 19, 2022. It is not reported as exploited. Patch Radar priority: High.
Mozilla developers Timothy Nikkel, Ashley Hale, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 105. 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 < 106.
