Hi,

The following vulnerability was published for gimp.

CVE-2026-58379[0]:
| A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser.
| This heap buffer overflow vulnerability allows a remote attacker to
| cause arbitrary code execution or a denial of service (DoS) by
| tricking a user into opening a specially crafted PSP image file. The
| vulnerability occurs because the software incorrectly calculates
| buffer sizes when processing low bit-depth images, leading to an
| overwrite of adjacent memory.


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