CVE-2026-42170

NVD: A heap-based buffer overflow vulnerability exists in the GIMP DDS (DirectDraw Surface) file parser. NVD: When a crafted DDS file declares a D3D9 pixel format but sets a lower bits-per-pixel (bpp) value in the header, the loader allocates an undersized heap buffer. NVD: Subsequent pixel data consumption at the real format's stride causes a write past the heap buffer boundary, leading to heap metadata corruption and potential code execution.
