Multiple CRLF injection vulnerabilities in PHPMailer before 5.2.14 allow attackers to inject arbitrary SMTP commands via CRLF sequences in an (1) email address to the validateAddress function in class.phpmailer.php or (2) SMTP command to the sendCommand function in class.smtp.php, a different vulnerability than CVE-2012-0796.
