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)");
