CVE-2026-108093 Red Hat CVE debrief

A flaw in GIMP's XCF loader causes a NULL pointer dereference when processing specially crafted XCF files with zero-size simulation parasites, leading to a denial of service. This vulnerability affects GIMP users, particularly those in environments where untrusted images are processed. The impact is limited to application crashes, and while exploitation is not confirmed, GIMP users should assess exposure and prioritize patching. The vulnerability's class and likely operational impact require review, especially in environments processing untrusted images.

Who should care

GIMP users, especially those in environments where untrusted images are processed, should assess exposure and prioritize patching. This includes operators, platform administrators, vulnerability management teams, and security teams who need to review the vulnerability's impact and implement necessary mitigations.

Why it matters

CVE-2026-108093 is a denial of service vulnerability in GIMP's XCF loader. While exploitation is not confirmed, GIMP users should assess exposure and prioritize patching, especially in environments processing untrusted images. The vulnerability's impact is limited to application crashes, but its exploitation could be used to disrupt service.

  • Denial of service via application crash
  • Potential for exploitation requires verification
  • Remediation priority for GIMP users
  • Exposure assessment for untrusted image processing environments

Technical summary

The XCF loader in GIMP processes image-simulation-intent and image-simulation-bpc parasites without ensuring the parasite data is present before dereferencing it. Opening a specially crafted XCF file with a zero-size simulation parasite can cause a NULL pointer dereference and crash the GIMP application. This vulnerability affects GIMP users, particularly those in environments where untrusted images are processed, and its impact is limited to application crashes. While exploitation is not confirmed, GIMP users should assess exposure and prioritize patching.

Defensive priority

Assess exposure and prioritize patching for GIMP users, especially in environments where untrusted images are processed.

Recommended defensive actions

  • Assess GIMP exposure in environments where untrusted images are processed
  • Prioritize patching for GIMP users
  • Monitor GIMP updates for security patches
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and source item provide details on the vulnerability, but do not specify affected or fixed versions, or confirm exploitation. GIMP users should verify their exposure and review the official advisory for guidance on patching and mitigation. The vulnerability's impact is limited to denial of service via application crashes, and its exploitation could be used to disrupt service. Defenders should focus on assessing exposure and prioritizing patching for GIMP users, especially in environments where untrusted images are a to
