CVE-2020-26968
First published: Tue Nov 17 2020(Updated: )
Mozilla developers Randell Jesup, Christian Holler, Jason Kratzer, Byron Campen, and Steve Fink reported memory safety bugs present in Firefox 82 and Firefox ESR 78.4. 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.
