Bug description:  PHP Payload in JPG Exif Header is Executed by PHP

Description:
------------
Affected Versions: PHP 5.1.4 and 4.4.2
The PHP server evaluates code inside a technically valid JPEG's
technically valid Exif header.  It'll evaluate it even if exif is not
compiled into PHP.

Reproduce code:
---------------
I need to attach it.

Expected result:
----------------
The POC jpg will write a file to the filesystem and include whatever PHP
code there is.  Anything is possible given the permissions of the web
server.

Actual result:
--------------
The POC jpg will write a file to the filesystem and include whatever PHP
code there is.  Anything is possible given the permissions of the web
