This morning, we returned to Infocon Green. As usual, we are raising the Infocon to alert you to emerging situations requiring immediate attention. PHP fit that description. By now, you either know about it, or you probably never will, so it is time to go back to "business as usual".
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.
