OpenLDAP -- incorrect handling of NULL in certificate Common Name

Description:

Jan Lieskovsky reports:

OpenLDAP does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority
