Technical details
The XCF loader leaves a dangling pointer in the linked-channels list when a channel with PROP_LINKED and PROP_SELECTION properties is destroyed, leading to a use-after-free (CWE-416). An attacker must trick a user into opening a specially crafted XCF file; exploitation then occurs in the user's security context without requiring elevated privileges.
