3. Description:

 

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access

Protocol) applications and development tools.

 

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 Red Hat Enterprise 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)

 

Users of OpenLDAP should upgrade to these updated packages, which contain

backported patches to resolve these issues. After installing this update,

the OpenLDAP daemons will be restarted automatically.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata

relevant to your system have been applied.
