PHP through 7.1.11 enables potential SSRF in applications that accept an
fsockopen or pfsockopen hostname argument with an expectation that the port
number is constrained. Because a :port syntax is recognized, fsockopen will
use the port number that is specified in the hostname argument, instead of
the port number in the second argument of the function.
