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 stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product writes data past the end, or before the beginning, of the intended buffer.
