-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== 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 Red Hat Enterprise Linux Server Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (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 6.
