FCGI does not perform range checks for file descriptors before use of the
FD_SET macro. This FD_SET macro could allow for more than 1024 total file
descriptors to be monitored in the closing state. This may allow remote
attackers to cause a denial of service (stack memory corruption, and infinite
loop or daemon crash) by opening many socket connections to the host and
crashing the service (CVE-2012-6687).");
