openldap-2.4.40-8.el7

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access
Protocol) applications and development tools. LDAP is a set of
protocols for accessing directory services (usually phone book style
information, but other information is possible) over the Internet,
similar to the way DNS (Domain Name System) information is propagated
over the Internet. The openldap package contains configuration files,
libraries, and documentation for OpenLDAP.

Security issues fixed with this release:

CVE-2015-3276
** RESERVED **
This candidate has been reserved by an organization or individual that
will use it when announcing a new security problem. When the
candidate has been publicized, the details for this candidate will be
provided.

Fixed bugs:

* 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.
Fixed 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.
* 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.
* 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.
Enhancements:

* OpenLDAP clients now automatically choose the Network Security Services (NSS) default cipher suites for communication with the server. It is no longer necessary to maintain the default cipher suites manually in the OpenLDAP source code.
