CVE-2022-27114

There is a vulnerability in htmldoc 1.9.16. In imageloadjpeg function image.cxx when it calls malloc,'img->width' and 'img->height' 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 jpegreadscanlines function.
