CVE-2026-106063
Gimp: gimp: heap buffer overflow in dicom export on oversized image dimensions
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, after integer overflow in the allocation size
Fixes and workarounds
Workaround
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.
