Mozilla Firefox is vulnerable to use-after-free vulnerability. This is possible with the frameloader during tree reconstruction while regenerating CSS layout when attempting to use a node in the tree that no longer exists. An attacker may exploit this issue to crash the affected application, resulting in a denial-of-service condition.
