Security Advisory: Moderate
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Updated redhat-ds-base packages that fix two security issues are now
available for Red Hat Directory Server 8.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
Red Hat Directory Server is an LDAPv3 compliant server. The base packages
include the Lightweight Directory Access Protocol (LDAP) server and
command-line utilities for server administration.
A flaw was found in the way Red Hat Directory Server handled password
changes. If an LDAP user had changed their password, and the directory
server had not been restarted since that change, an attacker able to bind
to the directory server could obtain the plain text version of that user's
password via the "unhashed#user#password" attribute. (CVE-2012-2678)
It was found that when the password for an LDAP user was changed, and audit
logging was enabled (it is disabled by default), the new password was
written to the audit log in plain text form. This update introduces a new
configuration parameter, "nsslapd-auditlog-logging-hide-unhashed-pw", which
when set to "on" (the default option), prevents Red Hat Directory Server
from writing plain text passwords to the audit log. This option can be
configured in "/etc/dirsrv/slapd-[ID]/dse.ldif". (CVE-2012-2746)
All users of Red Hat Directory Server 8 are advised to upgrade to these
updated packages, which resolve these issues. After installing this update,
the dirsrv service will be restarted automatically.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
