RedHat: RHSA-2011-0346:01 Moderate: openldap security and bug fix update
Summary
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)
This update also fixes the following bug:
* Previously, multiple concurrent connections to an OpenLDAP server could
cause the slapd service to terminate unexpectedly with an assertion error.
This update adds mutexes to protect multiple threads from accessing a
structure with a connection, and the slapd service no longer crashes.
(BZ#677611)
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.
