HTMLDOC before 1.9.19 has an out-of-bounds write in parse_paragraph in ps-pdf.cxx because of an attempt to strip leading whitespace from a whitespace-only node.
An Out of Bounds flaw was discovered in htmodoc 1.9.12 in function parse_tree() in toc.cxx, this possibly leads to memory layout information leaking in the data. This might be used in a chain of vulnerability in order to reach code execution.
A flaw was discovered in htmodoc 1.9.12 in function parse_paragraph in ps-pdf.cxx ,this flaw possibly allows possible code execution and a denial of service via a crafted file.
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 blosmaller than the expected size, and it will cause a buffer overflow/Address boundary error in the jpeg_read_scanlines function.
A flaw was found in htmldoc commit 31f7804. A heap buffer overflow in the function pdf_write_names in ps-pdf.cxx may lead to arbitrary code execution and Denial of Service (DoS).
In HTMLDOC 1.9.14, an infinite loop in the gif_read_lzw function can lead to a pointer arbitrarily pointing to heap memory and resulting in a buffer overflow.
A flaw was found in htmldoc before v1.9.12. Heap buffer overflow in pspdf_prepare_outpages(), in ps-pdf.cxx may lead to execute arbitrary code and denial of service.
A flaw was found in htmldoc in v1.9.12. Double-free in function pspdf_export(),in ps-pdf.cxx may result in a write-what-where condition, allowing an attacker to execute arbitrary code and denial of service.
Null pointer dereference in the htmldoc v1.9.11 and before may allow attackers to execute arbitrary code and cause a denial of service via a crafted html file.
A flaw was found in htmldoc in v1.9.12. Heap buffer overflow in render_table_row(),in ps-pdf.cxx may lead to arbitrary code execution and denial of service.
A flaw was found in htmldoc in v1.9.12 and prior. A stack buffer overflow in parse_table() in ps-pdf.cxx may lead to execute arbitrary code and denial of service.
A security issue was found in htmldoc v1.9.12 and before. A NULL pointer dereference in the function image_load_jpeg() in image.cxx may result in denial of service.
A flaw was found in htmldoc in v1.9.12 and before. Null pointer dereference in file_extension(),in file.c may lead to execute arbitrary code and denial of service.
A flaw was found in htmldoc in v1.9.12. Heap buffer overflow in pspdf_prepare_page(),in ps-pdf.cxx may lead to execute arbitrary code and denial of service.
A vulnerability was found in htmldoc version 1.9.15 where the stack out-of-bounds read takes place in gif_get_code() and occurs when opening a malicious GIF file, which can result in a crash (segmentation fault).
A stack-based buffer overflow in image_load_bmp() in HTMLDOC <= 1.9.13 results in remote code execution if the victim converts an HTML document linking to a crafted BMP file.
