CVE-2026-40917

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 flaw was found in GIMP. A remote attacker could exploit an integer overflow vulnerability in the FITS image loader by providing a specially crafted FITS file. This integer overflow leads to a zero-byte memory allocation, which is then subjected to a heap buffer overflow when processing pixel data. Successful exploitation could result in a denial of service (DoS) or potentially arbitrary code execution.(CVE-2026-40915)

A flaw was found in GIMP. This vulnerability, a heap buffer over-read in the icns_slurp() function, occurs when processing specially crafted ICNS image files. An attacker could provide a malicious ICNS file, potentially leading to application crashes or information disclosure on systems that process such files.(CVE-2026-40917)
