CVE-2026-58379 (GCVE-0-2026-58379)

Vulnerability from cvelistv5 – Published: 2026-07-03 18:29 – Updated: 2026-07-13 10:55

Title

Gimp: gimp: heap buffer overflow in read_channel_data()

Summary

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.

Severity

7.3 (High)
