What is CVE-2026-106063?

A heap-based buffer overflow vulnerability exists in GIMP's DICOM export plug-in. When an image with extraordinarily large dimensions is exported, a buffer is allocated based on the 32-bit product of width, height, and bytes-per-pixel. This can lead to an overflow as GEGL writes the complete uncompressed data into a buffer that is insufficiently sized due to an integer overflow during the allocation process.
