## Description

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 stream\_get\_meta\_data can be controlled if the input can be
controlled (e.g., during file uploads). For example, a "$uri =
stream\_get\_meta\_data(fopen($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.
