Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A flaw was found in GIMP. The PlayStation TIM loader, responsible for handling PlayStation image files, incorrectly calculates the size of the Color Look-Up Table (CLUT) due to an integer overflow. This occurs when multiplying num_colors and num_cluts, both 16-bit unsigned short integers, resulting in a value exceeding the maximum integer limit. An attacker could exploit this by providing a specially crafted image file, leading to undefined behavior and causing the GIMP plug-in to abort, effectively resulting in a denial of service.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-190

An arithmetic operation produces a value too large for its type and wraps around to an unexpected — often tiny or negative — number. That miscalculated value then drives a memory allocation or a bounds check, opening the door to corruption. The fix is checked arithmetic and validating sizes before they're used.

Recommended fix Moderate confidence

A GIMP version newer than 3.2.6 that includes the fix for the TIM loader integer overflow (specific version number to be confirmed from upstream sources)

  1. 1. Identify the current GIMP version installed using 'gimp --version' or checking your package manager
  2. 2. Check gitlab.gnome.org for GIMP releases following version 3.2.6 that address the TIM loader integer overflow vulnerability
  3. 3. For Red Hat Enterprise Linux users, check Red Hat's CVE database (access.redhat.com) for errata or security advisories related to CVE-2026-59089
  4. 4. If a fixed GIMP version is available from the upstream project, download from gitlab.gnome.org or use your distribution's package manager to upgrade
  5. 5. Verify the upgrade was successful by checking the GIMP version
  6. 6. Test the PlayStation TIM loader functionality with a legitimate TIM image file to confirm the fix does not break normal operation
Caveat Minor: Verify TIM image loading still works correctly after upgrade, as the fix may alter memory allocation behavior

No vendor fix exists Enterprise Linux has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
