CentOS Errata and Security Advisory CESA-2005:751-01
OpenLDAP is an open source suite of LDAP (Lightweight Directory Access
Protocol) applications and development tools.
The nss_ldap module is an extension for use with GNU libc which allows
applications to, without internal modification, consult a directory service
using LDAP to supplement information that would be read from local files
such as /etc/passwd, /etc/group, and /etc/shadow.
A bug was found in the way OpenLDAP, nss_ldap, and pam_ldap refer LDAP
servers. If a client connection is referred to a different server, it is
possible that the referred connection will not be encrypted even if the
client has “ssl start_tls” in its ldap.conf file. The Common
Vulnerabilities and Exposures project has assigned the name CAN-2005-2069
to this issue.
A bug was also found in the way certain OpenLDAP authentication schemes
store hashed passwords. A remote attacker could re-use a hashed password to
gain access to unauthorized resources. The Common Vulnerabilities and
Exposures project has assigned the name CAN-2004-0823 to this issue.
All users of OpenLDAP and nss_ldap are advised to upgrade to these updated
packages, which contain backported fixes that resolve these issues.
