A heap-based buffer overflow vulnerability exists in the GIMP DDS (DirectDraw Surface) file parser.

A heap-based buffer overflow vulnerability exists in the GIMP DDS (DirectDraw Surface) file parser. 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. Subsequent pixel data consumption at the real format's stride causes a write past the heap buffer boundary, leading to heap metadata corrupt
