The remote Red Hat host is missing one or more security updates.
Updated openldap packages that fix one security issue are now
available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
Moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.
OpenLDAP is an open source suite of Lightweight Directory Access
Protocol (LDAP) applications and development tools. LDAP is a set of
protocols used to access and maintain distributed directory
information services over an IP network. The openldap package contains
configuration files, libraries, and documentation for OpenLDAP.
A denial of service flaw was found in the way the OpenLDAP server
daemon (slapd) performed reference counting when using the rwm
(rewrite/remap) overlay. A remote attacker able to query the OpenLDAP
server could use this flaw to crash the server by immediately
unbinding from the server after sending a search request.
Red Hat would like to thank Michael Vishchers from Seven Principles AG
for reporting this issue.
All openldap users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue.
