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)"
