sendmail is vulnerable to authorization bypass. The vulnerability exists as a flaw was found in the way sendmail handled NUL characters in the CommonName field of X.509 certificates. An attacker able to get a carefully-crafted certificate signed by a trusted Certificate Authority could trick sendmail into accepting it by mistake, allowing the attacker to perform a man-in-the-middle attack or bypass intended client certificate authentication.
