CVE-2020-15673: Use After Free
First published: Tue Sep 22 2020(Updated: )
Mozilla developer Jason Kratzer reported memory safety bugs present in Firefox 80 and Firefox ESR 78.2. 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.
