The remote host is missing an update to openldap openldap2.3 announced via advisory DSA 1943-1.
Insight
Insight
It was discovered that OpenLDAP, a free implementation of the Lightweight Directory Access Protocol, when OpenSSL is used, 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. For the oldstable distribution (etch), this problem has been fixed in version 2.3.30-5+etch3 for openldap2.3. For the stable distribution (lenny), this problem has been fixed in version 2.4.11-1+lenny1 for openldap. For the testing distribution (squeeze), and the unstable distribution (sid), this problem has been fixed in version 2.4.17-2.1 for openldap. We recommend that you upgrade your openldap2.3/openldap packages.
