CVE-2026-106067 Red Hat CVE debrief

Who should care

Defenders responsible for GIMP installations, especially in environments where large images are processed, should assess exposure and prioritize verification and patching. This includes reviewing the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance, and checking relevant monitoring, detection, and logs for exposed assets that need extra review.

Why it matters

Defenders should prioritize verifying and patching GIMP installations, especially in environments where large images are processed, due to a heap-based buffer overflow in the Hot color filter plug-in.

• Potential for denial of service due to buffer overflow
• Need for verification of GIMP installations and image processing workflows
• Possible data corruption or unexpected behavior when processing large images

Technical summary

The vulnerability is caused by a heap-based buffer overflow in GIMP’s Hot color filter plug-in. For very large images, a pixel buffer is allocated using overflowing 32-bit width * height (and related) arithmetic while the filter’s pixel access path uses the true image size, after integer overflow in the allocation size. This can lead to potential denial of service, data corruption, or unexpected behavior when processing large images. Defenders should prioritize verifying and patching GIMP installations, especially in environments where large images are processed.

Defensive priority

Defenders should prioritize verifying and patching GIMP installations, especially in environments where large images are processed.

Recommended defensive actions

• Verify GIMP installations for potential exposure
• Assess image processing workflows for large image handling
• Monitor for patches or updates from GIMP or affected vendors
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed

Evidence notes

The CVE record and source item provide details on the heap-based buffer overflow in GIMP’s Hot color filter plug-in. However, specific version information and remediation steps are not provided. To verify and patch, defenders should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. They should also check relevant monitoring, detection, and logs for exposed assets that need extra review.
