Hi,

The following vulnerability was published for gimp.

CVE-2026-59089[0]:
| A flaw was found in GIMP. The PlayStation TIM loader, responsible
| for handling PlayStation image files, incorrectly calculates the
| size of the Color Look-Up Table (CLUT) due to an integer overflow.
| This occurs when multiplying num_colors and num_cluts, both 16-bit
| unsigned short integers, resulting in a value exceeding the maximum
| integer limit. An attacker could exploit this by providing a
| specially crafted image file, leading to undefined behavior and
| causing the GIMP plug-in to abort, effectively 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.
