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

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

A flaw was found in htmldoc before v1.9.12. Heap buffer overflow in pspdfprepareoutpages(), in ps-pdf.cxx may lead to execute arbitrary code and denial of service.

A flaw was found in htmldoc commit 31f7804. A heap buffer overflow in the function pdfwritenames 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 (writeheader) /htmldoc/htmldoc/html.cxx:273.

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

In HTMLDOC 1.9.14, an infinite loop in the gifreadlzw function can lead to a pointer arbitrarily pointing to heap memory and resulting in a buffer overflow.

A vulnerability was found in htmldoc version 1.9.15 where the stack out-of-bounds read takes place in gifgetcode() and occurs when opening a malicious GIF file, which can result in a crash (segmentation fault).

A stack-based buffer overflow in imageloadbmp() 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 imageloadbmp.

A flaw was discovered in htmodoc 1.9.12 in function parseparagraph 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 parsetree() 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.

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.

HTMLDOC before 1.9.19 has an out-of-bounds write in parseparagraph in ps-pdf.cxx because of an attempt to strip leading whitespace from a whitespace-only node.

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

A flaw was found in htmldoc in v1.9.12. Heap buffer overflow in rendertablerow(),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 before. Null pointer dereference in fileextension(),in file.c may lead to execute arbitrary code and denial of service.

A flaw was found in htmldoc in v1.9.12. Double-free in function pspdfexport(),in ps-pdf.cxx may result in a write-what-where condition, allowing an attacker to execute arbitrary code and denial of service.

Buffer Overflow vulnerability in writeheader in htmldoc through 1.9.11 allows attackers to casue a denial of service via /htmldoc/htmldoc/html.cxx:273.

Buffer overflow vulnerability in writenode in htmldoc through 1.9.11 allows attackers to cause a denial of service via htmldoc/htmldoc/html.cxx:588.
