Language:

Synopsis

The remote Red Hat host is missing a security update for 389-ds:1.4.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:3906 advisory.

389 Directory Server is an LDAP version 3 (LDAPv3) compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.

Security Fix(es):

* 389-ds-base: CRYPT password hash with asterisk allows any bind attempt to succeed (CVE-2021-3652)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* A replication connection can be erroneously flagged as a non-replication connection causing the evaluation of the access control rules (BZ#1993267).

* If a persistent search encounters an error entries were previously still being returned. This has been fixed (BZ#1993266).

* Indexes added by plugins are not enabled, and cause some plugins to perform unexpected internal unindexed searches. Now indexes added by plugins are enabled immediately (BZ#1993263).

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

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

Solution

Update the RHEL 389-ds:1.4 package based on the guidance in RHSA-2021:3906.
