Description Doran Moppert 2021-09-08 01:09:20 UTC 
Mozilla developers Tyson Smith and Gabriele Svelto reported memory safety bugs present in Firefox 91 and Firefox ESR 78.13. 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.
