RHBA-2017:0302 - Bug Fix Advisory

Topic

Updated sssd and ding-libs packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

The System Security Services Daemon (SSSD) service provides a set of daemons to manage access to remote directories and authentication mechanisms. It also provides the Name Service Switch (NSS) and the Pluggable Authentication Modules (PAM) interfaces toward the system, and a pluggable back-end system to connect to multiple different account sources.

The ding-libs packages contain a set of libraries used by the System Security Services Daemon (SSSD) and other projects and provide functions to manipulate filesystem pathnames (libpath_utils), a hash table to manage storage and access time properties (libdhash), a data type to collect data in a hierarchical structure (libcollection), a dynamically growing, reference-counted array (libref_array), and a library to process configuration files in initialization format (INI) into a library collection data structure (libini_config).

This update fixes the following bugs:

• Previously, the ding-libs library failed to read lines from *.ini files that do not match the "key = value" format. As a consequence, the System Security Services Daemons (SSSD) failed to read group policy objects (GPO) from *.ini files without an equal sign in attributes. The ding-libs library has been enhanced and now provides a flag to ignores lines in *.ini files that do not match the "key = value" format. Additionally, a patch has been applied to SSSD to use the new flag in the ding-libs library. As a result, SSSD no longer fails to process GPOs in the mentioned situation. (BZ#1379580, BZ#1379582)

Users of sssd and ding-libs are advised to upgrade to these updated packages, which fix these bugs.
