Hi,

The following vulnerability was published for gimp.

CVE-2026-59088[0]:
| A flaw was found in GIMP. A signed integer overflow vulnerability
| exists in the `file-fli` plugin when processing FLI image files.
| This occurs due to an incorrect calculation during memory allocation
| for image buffers, where the multiplication of image width and
| height can exceed the maximum integer value. A remote attacker could
| exploit this by tricking a user into opening a specially crafted FLI
| file, leading to the application crashing and resulting in a denial
| of service.


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