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

Fixes

Solution

No solution given by the vendor.


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.
