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

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

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 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 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 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.

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.
