Scientific Linux Security Update : openldap on SL6.x i386/x86_64

medium Nessus Plugin ID 60988

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

A flaw was found in the way OpenLDAP handled authentication failures being passed from an OpenLDAP slave to the master. If OpenLDAP was configured with a chain overlay and it forwarded authentication failures, OpenLDAP would bind to the directory as an anonymous user and return success, rather than return failure on the authenticated bind. This could allow a user on a system that uses LDAP for authentication to log into a directory-based account without knowing the password. (CVE-2011-1024)

It was found that the OpenLDAP back-ndb back end allowed successful authentication to the root distinguished name (DN) when any string was provided as a password. A remote user could use this flaw to access an OpenLDAP directory if they knew the value of the root DN. Note: This issue only affected OpenLDAP installations using the NDB back-end, which is only available for Scientific Linux 6 via third-party software. (CVE-2011-1025)

A flaw was found in the way OpenLDAP handled modify relative distinguished name (modrdn) requests. A remote, unauthenticated user could use this flaw to crash an OpenLDAP server via a modrdn request containing an empty old RDN value. (CVE-2011-1081)

After installing this update, the OpenLDAP daemons will be restarted automatically.

Solution

Update the affected packages.
