> DESCRIPTION:
> s.masugata has reported a vulnerability in PHP, which potentially can
> be exploited by malicious people to use it as an open mail relay.
>
> The vulnerability is caused due to an input validation error in the
> "mb_send_mail()" function. This can be exploited to inject arbitrary
> headers in a mail sent via a script calling the "mb_send_mail()"
> function where the "To" parameter can be controlled by the attacker.
>
> SOLUTION:
> Update to version 5.1.0.
> http://www.php.net/downloads.php
>
> Do not call the "mb_send_mail()" function in scripts where input
> passed to the "To" parameter originates from untrusted sources.
