NVD Description
Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Oracle.
See How to fix? for Oracle:7 relevant fixed versions and status.
Mozilla developers reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. 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. This vulnerability affects Thunderbird < 78.11, Firefox < 89, and Firefox ESR < 78.11.
