Jan Lieskovsky reports:

OpenLDAP does not properly handle a β€˜\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
