Name of the Vulnerable Software and Affected Versions
Firefox ESR versions prior to 91.5

Description
The issue is related to a use-after-free error, which could lead to a potentially exploitable crash. This occurs due to certain network request objects being freed too early when releasing a network request handle. The vulnerability is also associated with the function ChannelEventQueue::mOwner in the affected software, where memory is used after it has been freed. Exploitation of this issue could allow a remote attacker to cause a use-after-free error and potentially execute arbitrary code on the system.

For Firefox versions prior to 96, update to version 96 or later.
For Thunderbird versions prior to 91.5, update to version 91.5 or later.
