Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for openldap.

CVE-2009-3767[0]:
| libraries/libldap/tls_o.c in OpenLDAP, 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, a
| related issue to CVE-2009-2408.


Please coordinate with the security team (team at security.debian.org) to
prepare packages for the stable and oldstable releases.
