Virtuozzo 6 : 389-ds-base / 389-ds-base-devel / 389-ds-base-libs (VZLSA-2017-0893)
High Nessus Plugin ID 101444
SynopsisThe remote Virtuozzo host is missing a security update.
DescriptionAn 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)
