CVE-2016-10712 Information

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.
