CVE-2026-106061 Red Hat CVE debrief

A flaw in GIMP's X cursor (XMC) thumbnail loader can cause a heap buffer over-read when processing a crafted XMC file, potentially crashing GIMP or corrupting process memory. This issue arises from an integer overflow in size calculation, leading to an undersized pixel buffer allocation. GIMP users, especially in environments where untrusted images are processed, should assess exposure and prioritize patching. The vulnerability's impact includes potential GIMP crashes or process memory corruption, necessitating a review of GIMP versions and configurations for exposure.

Who should care

GIMP users, especially those in environments where untrusted images are processed, should assess exposure and prioritize patching. This includes reviewing GIMP versions and configurations for potential vulnerabilities and implementing compensating controls for image processing environments. The vulnerability's impact on operational security and potential for GIMP crashes or process memory corruption necessitates prompt attention and mitigation.

Why it matters

A flaw in GIMP's X cursor (XMC) thumbnail loader can cause a heap buffer over-read when processing a crafted XMC file, potentially crashing GIMP or corrupting process memory. GIMP users, especially those in environments where untrusted images are processed, should assess exposure and prioritize patching.

  • Potential GIMP crashes or process memory corruption
  • Need to verify GIMP versions and configurations for exposure
  • Priority on patching and updating GIMP to the latest version
  • Possible impact on image processing environments

Technical summary

The vulnerability occurs in GIMP's X cursor (XMC) thumbnail loader, where a crafted XMC file can cause a heap buffer over-read due to an integer overflow in the size calculation. This leads to an undersized pixel buffer allocation, allowing for potential out-of-bounds reads on the heap. The issue can result in GIMP crashes or process memory corruption, emphasizing the need for users to assess exposure and prioritize patching. The vulnerability is classified as MEDIUM with a CVSS score of 5.5, and its exploitation could have operational impacts on image processing environments.

Defensive priority

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

Recommended defensive actions

  • Assess GIMP exposure and prioritize patching
  • Review and update GIMP to the latest version
  • Implement compensating controls for image processing environments
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and source item provide details on the vulnerability, but information on exploitation and impact is limited. There is no evidence of public exploitation, but defenders should verify GIMP versions and configurations for exposure. The vulnerability affects GIMP's X cursor (XMC) thumbnail loader, and its severity is classified as MEDIUM with a CVSS score of 5.5. Supplied sources include the CVE Program record and NIST NVD detail page.
