3. Description:
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)
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing this update, the 389 server service will be restarted
automatically.
5. Bugs fixed (https://bugzilla.redhat.com/):
1435365 - Unable to dereference unqiemember attribute because it is dn [#UID] not dn syntax
1436575 - CVE-2017-2668 389-ds-base: Remote crash via crafted LDAP messages
