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.
When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to be notified. This results in a use-after-free and we presume that with enough effort it could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.
