note 116613 added to function.gethostbyname

On January 27, 2015 a critical security vulnerability (remote code execution possible in certain circumstances) was found in glibc's 'gethostbyname' function. This vulnerability was coined GHOST. This can also affect Linux servers running PHP that haven't been patched. Quick test to see if your server is vulnerable for a GHOST attack: php -r '$e="0";for($i=0;$i<2500;$i++)$e="0$e"; gethostbyname($e);' If you get 'Segmentation fault', then your server is vulnerable.
