Mozilla developers Tyson Smith and Gabriele Svelto reported memory safety bugs present in 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 (CVE-2021-38493). The firefox package has been updated to the 91ESR branch. See the upstream release notes for details.
