-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openldap security and bug fix update Advisory ID: RHSA-2014:0126-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0126.html Issue date: 2014-02-03 CVE Names: CVE-2013-4449 ===================================================================== 1. Summary: Updated openldap packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, 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: OpenLDAP is an open source suite of Lightweight Directory Access Protocol (LDAP) applications and development tools. LDAP is a set of protocols used to access and maintain distributed directory information services over an IP network. The openldap package contains configuration files, libraries, and documentation for OpenLDAP. A denial of service flaw was found in the way the OpenLDAP server daemon (slapd) performed reference counting when using the rwm (rewrite/remap) overlay. A remote attacker able to query the OpenLDAP server could use this flaw to crash the server by immediately unbinding from the server after sending a search request. (CVE-2013-4449) Red Hat would like to thank Michael Vishchers from Seven Principles AG for reporting this issue. This update also fixes the following bug: * Previously, OpenLDAP did not properly handle a number of simultaneous updates. As a consequence, sending a number of parallel update requests to the server could cause a deadlock. With this update, a superfluous locking mechanism causing the deadlock has been removed, thus fixing the bug. (BZ#1056124) All openldap users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1019490 - CVE-2013-4449 openldap: segfault on certain queries with rwm overlay 6.
