Description

There is a vulnerability in htmldoc 1.9.16. In image_load_jpeg function image.cxx when it calls malloc,&#39;img->width&#39; and &#39;img->height&#39; they are large enough to cause an integer overflow. So, the malloc function may return a heap blosmaller than the expected size, and it will cause a buffer overflow/Address boundary error in the jpeg_read_scanlines function.
