"The remote host is running a version of PHP that is older than 4.3.2.

There is a flaw in this version that could allow an attacker who has the 
ability to inject an arbitrary argument to the function 
socket_iovec_alloc() to crash the remote service and possibly to execute 
arbitrary code.

For this attack to work, PHP has to be compiled with the option
--enable-sockets (which is disabled by default), and an attacker needs 
to be able to pass arbitrary values to socket_iovec_alloc().

Other functions are vulnerable to such flaws : openlog(), socket_recv(), 
socket_recvfrom() and emalloc()");
