Description Doran Moppert 2020-08-26 02:46:11 UTC

Mozilla developers Jason Kratzer, Christian Holler, Byron Campen, Tyson Smith reported memory safety bugs present in Firefox 79 and Firefox ESR 78.1. 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.
