Vulnerability Assessment Details

php socket_iovec_alloc() integer overflow

Vulnerability Assessment Summary
Checks for version of PHP

Detailed Explanation for this Vulnerability Assessment

The remote host is running a version of PHP which is
older than 4.3.2

There is a flaw in this version which may permit a possible hacker 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 a possible hacker 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()

Solution : Upgrade to PHP 4.3.2
Network Security Threat Level: Low

Networks Security ID: 7187, 7197, 7198, 7199, 7210, 7256, 7259
