How to fix?

Upgrade Ubuntu:14.04 php5 to version 5.5.9+dfsg-1ubuntu4.24 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php5 package and not the php5 package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

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.
