Hi,

The following vulnerability was published for gimp.

CVE-2026-66757[0]:
| A flaw was found in the file-sgi plugin in GIMP. When processing an
| RLE-compressed SGI image, the plugin allocates memory for a row
| table. The image header dimensions (ysize and zsize) are read as
| 16-bit unsigned integers. If a crafted file sets both dimensions to
| their maximum value (65535), the multiplication ysize * zsize
| overflows the standard 32-bit int boundary before being passed to
| calloc. This integer overflow issue results in undefined behavior,
| aborting the plugin and causing 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.
