Hi,

The following vulnerability was published for gimp.

CVE-2026-82324[0]:
| A flaw was found in the file-iff (IFF/ILBM) plugin in GIMP. When
| processing a specially crafted IFF/ILBM image file, the plugin does
| not properly validate the HAM row size and improperly handles cases
| where the number of color planes (nPlanes) is zero. This causes a
| row size mismatch that bypasses memory bounds checking, resulting in
| heap out-of-bounds reads. This issue can result in an application
| crash, leading to a denial of service or a limited information
| disclosure of heap memory contents.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
