NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

Mozilla developers and community members reported memory safety bugs present in Firefox 68 and Firefox ESR 68. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.
