RHSA-2026:80509 - Security Advisory

Topic

An update for gimp is now available for Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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: gimp: Heap buffer overflow in read_channel_data() (CVE-2026-58379)
• gimp: gimp: Stack buffer overflow in pnmscanner_gettoken() (CVE-2026-58380)
• gimp: GIMP: Arbitrary code execution in PSD plugin due to unsigned underflow (CVE-2026-59090)
• gimp: gimp: Integer overflow in read_RLE_channel() (CVE-2026-58384)
• gimp: integer overflow in file-fits plugin causes a heap-based buffer overflow on crafted FITS images (CVE-2026-66758)
• gimp: GIMP: Arbitrary code execution via crafted TIF file parsing (CVE-2026-18304)
• gimp: GIMP: Remote code execution via PSD file parsing integer overflow (CVE-2026-18301)
• gimp: GIMP: Remote code execution via TIF file parsing heap-based buffer overflow (CVE-2026-18302)
• gimp: GIMP: Remote Code Execution via TIF file parsing integer overflow (CVE-2026-18305)
• gimp: GIMP: Remote code execution via TIF file parsing vulnerability (CVE-2026-18303)
• gimp: GIMP: Remote Code Execution via SGI File Parsing Integer Overflow (CVE-2026-18306)
• gimp: GIMP: Remote code execution via TIF file parsing heap-based buffer overflow (CVE-2026-18307)
