Descripción:	Summary: The remote host is missing an update for the 'openldap' package(s) announced via the referenced advisory. Vulnerability Insight: 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 packages contain configuration files, libraries, and documentation for OpenLDAP. A flaw was found in the way OpenLDAP parsed OpenSSL-style cipher strings. As a result, OpenLDAP could potentially use ciphers that were not intended to be enabled. (CVE-2015-3276) This issue was discovered by Martin Poole of the Red Hat Software Maintenance Engineering group. The openldap packages have been upgraded to upstream version 2.4.40, which provides a number of bug fixes and one enhancement over the previous version: * The ORDERING matching rules have been added to the ppolicy attribute type descriptions. * The server no longer terminates unexpectedly when processing SRV records. * Missing objectClass information has been added, which enables the user to modify the front-end configuration by standard means. (BZ#1147982) This update also fixes the following bugs: * 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#1125152) * The httpd service sometimes terminated unexpectedly with a segmentation fault on the libldap library unload. The underlying source code has been modified to prevent a bad memory access error that caused the bug to occur. As a result, httpd no longer crashes in this situation. (BZ#1158005) * After upgrading the system from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7, symbolic links to certain libraries unexpectedly pointed to locations belonging to the openldap-devel package. If the user uninstalled openldap-devel, the symbolic links were broken and the 'rpm -V openldap' command sometimes produced errors. With this update, the symbolic links no longer get broken in the described situation. If the user downgrades openldap to version 2.4.39-6 or earlier, the symbolic links might break. After such downgrade, it is recommended to verify that the symbolic links did not break. To do this, make sure the yum-plugin-verify package is installed and obtain the target libraries by running the 'rpm -V openldap' or 'yum verify openldap' command. (BZ#1230263) In addition, this update adds the following enhancement: * OpenLDAP clients now automatically choose the Netwo ...
