Name of the Vulnerable Software and Affected Versions Firefox ESR versions prior to 68.12 Thunderbird versions prior to 68.12

Description The issue is related to a use-after-free error, which occurs when memory is accessed after it has been freed. This could potentially allow a remote attacker to execute arbitrary code by using a specially crafted web page. The error happens when an operation, such as a fetch, is aborted, and an abort signal is deleted while notifying objects, resulting in a use-after-free situation.

Recommendations For Firefox ESR versions prior to 68.12, update to version 68.12 or later. For Thunderbird versions prior to 68.12, update to version 68.12 or later.
