Ruby is vulnerable to man-in-the-middle attack. The SSL client’s hostname identity check does not properly handle certificates with hostnames containing NULL bytes. A remote attacker, who has obtained a specific certificate that is signed by an trusted CA, is able to exploit the vulnerability to perform man-in-the-middle attacks or spoof SSL servers.
