PHP is prone to an email-header-injection vulnerability because it fails to properly sanitize user-supplied input when constructing email messages.

Exploiting this issue allows a malicious user to create arbitrary email headers, and then create and transmit spam messages from the affected computer.

The following versions are vulnerable:

PHP 4 up to and including 4.4.6
PHP 5 up to and including 5.2.1

<?php
   mail("test@domain(dot)com", "Test\r\n \nAnother-Header: Blub", "Message");
?>
