RHSA-2005-751: nss_ldap Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the nss_ldap packages
Detailed Explanation for this Vulnerability Test
Updated openldap and nss_ldap packages that correct a potential password
disclosure issue are now available.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
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 CVE-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 CVE-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.
