Topic

Updated redhat-ds-base packages that fix one security issue are now available
for Red Hat Directory Server 8.

The Red Hat Security Response Team has rated this update as having
important 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.

Description

The redhat-ds-base packages provide Red Hat Directory Server, which is an
LDAPv3 compliant server. The base packages include the Lightweight
Directory Access Protocol (LDAP) server and command-line utilities for
server administration.

It was discovered that the Red Hat Directory Server did not properly handle
certain Get Effective Rights (GER) search queries when the attribute list,
which is a part of the query, included several names using the '@'
character. An attacker able to submit search queries to the Red Hat
Directory Server could cause it to crash. (CVE-2013-4485)

All Red Hat Directory Server 8 users are advised to upgrade to these
updated packages, which contain a backported patch to correct this issue.
After installing this update, the dirsrv service will be restarted
automatically.
