Virtuozzo 6 : 389-ds-base / 389-ds-base-devel / 389-ds-base-libs (VZLSA-2017-0893)

High Nessus Plugin ID 101444


The remote Virtuozzo host is missing a security update.


An update for 389-ds-base is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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) :

* An invalid pointer dereference flaw was found in the way 389-ds-base handled LDAP bind requests. A remote unauthenticated attacker could use this flaw to make ns-slapd crash via a specially crafted LDAP bind request, resulting in denial of service. (CVE-2017-2668)

Red Hat would like to thank Joachim Jabs (F24) for reporting this issue.

Bug Fix(es) :

* Previously, the 'deref' plug-in failed to dereference attributes that use distinguished name (DN) syntax, such as 'uniqueMember'. With this patch, the 'deref' plug-in can dereference such attributes and additionally 'Name and Optional UID' syntax. As a result, the 'deref' plug-in now supports any syntax. (BZ#1435365)

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected 389-ds-base / 389-ds-base-devel / 389-ds-base-libs package.
