Description Anten Skrabec 2022-05-09 19:21:46 UTC 
There is a vulnerability in htmldoc 1.9.16. In image_load_jpeg 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 blop smaller than the expected size, and it will cause a buffer overflow/Address boundary error in the jpeg_read_scanlines function.
