CVE-2026-106063

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
