HTMLDOC 1.9.7 allows a stack-based buffer overflow in the hd_strlcpy() function in string.c (when called from render_contents in ps-pdf.cxx) via a crafted HTML document.

Integer overflow in the htmldoc 1.9.11 and before may allow attackers to execute arbitrary code and cause a denial of service that is similar to CVE-2017-9181.

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.

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 and before. Null pointer dereference in file_extension(),in file.c 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 prior. A stack buffer overflow in parse_table() in ps-pdf.cxx 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 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.

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 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.

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 stack-based buffer under-read in htmldoc before 1.9.12, allows attackers to cause a denial of service via a crafted BMP image to image_load_bmp.

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.

A heap buffer overflow in image_set_mask function of HTMLDOC before 1.9.15 allows an attacker to write outside the buffer boundaries.

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).

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.

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).

HTMLDoc v1.9.15 was discovered to contain a heap overflow via (write_header) /htmldoc/htmldoc/html.cxx:273.

HTMLDoc v1.9.12 and below was discovered to contain a heap overflow via e_node htmldoc/htmldoc/html.cxx:588.

HTMLDOC v1.9.18 contains a buffer overflow in parse_pre function,ps-pdf.cxx:5681.
