The Positive Technologies researchers report there is a working exploit for GHOST vulerability against the popular phpBB forum. The exploit in gethostbyname function allows an attacker to gain full control over an operating system of the vulnerable server. PhpBB is a well-known forum tool for websites. A quick Google search shows that this system is currently installed in more than 800,000 websites.

Of course, not all of them are vulnerable to GHOST, as it requires that several factors be taken into account. However, rich mechanisms to maintain host identification allow an attacker to create a specially crafted exploit via http and achieve almost 100% success in conducting this attack.
