Hans Jerry Illikainen reports :

A heap overflow may occur in the giffix utility included in giflib-5.1.1 when processing records of the type `IMAGE_DESC_RECORD_TYPE' due to the allocated size of `LineBuffer' equaling the value of the logical screen width, `GifFileIn->SWidth', while subsequently having `GifFileIn->Image.Width' bytes of data written to it.
