Red Hat Security Advisory

 

Synopsis: Important: 389-ds-base security and bug fix update

Advisory ID: RHSA-2017:0893-01

Product: Red Hat Enterprise Linux

Advisory URL: https://access.redhat.com/errata/RHSA-2017:0893

Issue date: 2017-04-11

CVE Names: CVE-2017-2668

=====================================================================

 

1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64

Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64

Red Hat Enterprise Linux Server (v. 6) - i386, x86_64

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
