Detailsinfo

A vulnerability has been found in GIMP (affected version not known) and classified as critical. This vulnerability affects some unknown functionality of the component PSP Image Handler. The manipulation with an unknown input leads to a heap-based overflow vulnerability. The CWE definition for the vulnerability is CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at access.redhat.com. This vulnerability was named CVE-2026-58379 since 06/30/2026. The exploitation appears to be easy. The attack can be initiated remotely.
