CVE-2026-106063
CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:H
Summary
A heap-based buffer overflow was found in GIMP’s DICOM export plug-in. When exporting an image with extremely large width and height, the export path allocates a buffer using a 32-bit width * height (and bytes-per-pixel) product that can overflow. GEGL then writes the full uncompressed extent into the undersized buffer (CWE-787), after integer overflow in the allocation size
Affected Software
| Vendor | Product | Version Range | Status |
|---|
Weaknesses
- CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer
Workarounds
To mitigate this avoid exporting untrusted or unnecessarily huge images to DICOM; cap image dimensions in workflows that process third-party content. Use checked multiplication and maximum dimension limits in custom automation that drives GIMP export.
