Synopsis

The remote Red Hat host is missing one or more security updates for redhat-ds-base.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:1041 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL redhat-ds-base package based on the guidance in RHSA-2012:1041.
