CVE-2026-18301

The GIMP is an image composition and editing program, which can be used for creating logos and other graphics for Web pages. The GIMP offers many tools and filters, and provides a large image manipulation toolbox, including channel operations and layers, effects, subpixel imaging and antialiasing, and conversions, together with multilevel undo. The GIMP offers a scripting facility, but many of the included scripts rely on fonts that we cannot distribute.

Security Fix(es):

A vulnerability was found in GIMP (Image Processing Software) (affected version unknown). It has been classified as critical. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value.

GIMP PSD File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PSD files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29395.
