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.


If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.
