Hi,

The following vulnerability was published for gimp.

CVE-2026-106063[0]:
| 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


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
