Description
A use-after-free issue can occur when a script uses mutation events to move DOM nodes between documents. This results in the old document that held the node being freed, but the node still having a pointer referencing it, leading to a potentially exploitable crash. The vulnerability is related to the use of memory after it has been freed, which can allow a remote attacker to impact the confidentiality, integrity, and availability of protected information.

For Thunderbird versions prior to 52.9, update to version 52.9 or later.
