Impact

An attacker can crash GIMP or potentially execute arbitrary code with the permissions of the local user. They need a user to open a maliciously crafted XCF image file.

NVD description

A flaw was found in GIMP. The XCF loader can leave a dangling pointer in the linked-channels list when a linked channel is later destroyed via a selection property. Opening a crafted XCF file can cause a use-after-free in the main GIMP process, leading to a crash and potentially arbitrary code execution.
