CVE-2016-10712

In PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x before 7.0.3, all of the return values of streamgetmetadata can be controlled if the input can be controlled (e.g., during file uploads). For example, a "$uri = streamgetmetadata(fopen($file, "r"))['uri']" call mishandles the case where $file is data:text/plain;uri=eviluri, -- in other words, metadata can be set by an attacker.
