GIMP PSP Parser Heap Overflow Arbitrary Code Execution
CVE-2026-58379 Published on July 3, 2026

Gimp: gimp: heap buffer overflow in read_channel_data()
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.
