CVE-2016-5114

http://seclists.org/oss-sec/2016/q2/426

As explained in the www.search-lab.hu post (in the section between "We
found the answer by reviewing the source code" and "And here we are"),
there was really only one underlying problem: the code misinterpreted
the semantics of the snprintf return value. Use CVE-2016-5114. The
other outcomes were consequences of this. The "memory leak" is the
same as the "out-of-boundaries read": extra bytes from process memory
were being written to a log file that might be readable by untrusted
users. The "buffer overflow" is the same as the "wrote a \n character
outside of the allocated memory."
