What is CVE-2026-80101?

A flaw exists in the file-xwd plugin of GIMP where the processing of specially crafted XWD image files results in improper validation of the image width and bytes-per-line parameters. This independent validation leads to discrepancies in their combined values, causing inadequate bounds checking. Consequently, this vulnerability can lead to an application crash and may allow for a denial of service attack or limited information leakage from the heap memory, jeopardizing the integrity of user data.
