SANS Internet Storm Center Version 6 imported change current

Imported from official source

PHP.net announced that it will release a critical update today. We decided to change the infoCon to YELLOW due to the widespread use of PHP, the expected severity of the flaw (CVSS 9.4), and the availability of early PoC exploits before the patch became available.
