A flaw was found in libmicrohttpd. A missing bounds check in the
post_process_urlencoded function leads to a buffer overflow, allowing a
remote attacker to write arbitrary data in an application that uses
libmicrohttpd. The highest threat from this vulnerability is to data
confidentiality and integrity as well as system availability. Only version
0.9.70 is vulnerable.
