Title

Gimp: out-of-bounds read in file-icns plugin causes information disclosure or crash on crafted icns images

Summary

A flaw was found in the file-icns plugin in GIMP. When applying a decompressed mask during ICNS image processing, the plugin reads from the mask data buffer without verifying if the cursor exceeds the allocated resource size. If a crafted file contains a truncated mask resource, the icns_decompress function continues reading past the bounds of the buffer. This out-of-bounds read vulnerability results in information disclosure of heap contents, where memory contents are leaked as alpha channel pixel values, or a crash leading to a denial of service if unmapped memory is accessed.

Severity

Vulnerability from osv_almalinux – Published: 2026-08-05 00:00 – Updated: 2026-08-06 13:11 – Source website

Summary

Important: gimp security update

Details

The GIMP (GNU Image Manipulation Program) is an image composition and editing program. GIMP provides a large image manipulation toolbox, including channel operations and layers, effects, sub-pixel imaging and anti-aliasing, and conversions, all with multi-level undo.

Security Fix(es):

gimp: GIMP APNG loader heap-buffer-overflow when fcTL width exceeds IHDR width (file-png.c) (CVE-2026-42169)
gimp: integer overflow in file-fits plugin causes a heap-based buffer overflow on crafted FITS images (CVE-2026-66758)
gimp: out-of-bounds read in file-icns plugin causes information disclosure or crash on crafted ICNS images (CVE-2026-66759)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Summary

gimp security update

Details

GIMP is a cross-platform image editor available for GNU/Linux, OS X, Windows and more operating systems. It is free software, you can change its source code and distribute your changes. Whether you are a graphic designer, photographer, illustrator, or scientist, GIMP provides you with sophisticated tools to get your job done. You can further enhance your productivity with GIMP thanks to many customization options and 3rd party plugins.

Security Fix(es):

(CVE-2026-59087)

(CVE-2026-59088)

A flaw was found in the file-sgi plugin in GIMP. When processing an RLE-compressed SGI image, the plugin allocates memory for a row table. The image header dimensions (ysize and zsize) are read as 16-bit unsigned integers. If a crafted file sets both dimensions to their maximum value (65535), the multiplication ysize * zsize overflows the standard 32-bit int boundary before being passed to calloc. This integer overflow issue results in undefined behavior, aborting the plugin and causing a denial of service.(CVE-2026-66757)

A flaw was found in the file-fits plugin in GIMP. When processing a FITS image file, the plugin calculates memory allocation sizes using signed 32-bit integers for width and height. If a crafted file sets both values to large values, their product exceeds 2^31 and overflows, resulting in an undersized heap-based buffer allocation. This integer overflow issue results in a heap-based buffer overflow when cfitsio subsequently writes a full row of pixels in the buffer, causing memory corruption, potentially leading to arbitrary code execution or a denial of service.(CVE-2026-66758)

Severity

7.8 (High)
