Hi,

The following vulnerability was published for gimp.

CVE-2026-106062[0]:
| A heap-based buffer overflow was found in GIMP’s DirectDraw Surface
| (DDS) loader. When loading a crafted DDS image, buffer sizes derived
| from width, height, and pitch can be computed using 32-bit
| arithmetic that overflows. The allocated buffer is too small for the
| amount of pixel data written through GEGL (CWE-787), following
| integer overflow in size calculations (CWE-190). This may allow heap
| corruption and, in the worst case, arbitrary code execution in the
| context of the GIMP process.


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