CVE-2022-46878
First published: Tue Dec 13 2022(Updated: )
Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 107 and Firefox ESR 102.5. 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.
