Red Hat Enterprise Linux 6: RHSA-2018:1877-01 Moderate: SSSD Input Issue

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) as well as other projects, and provide functions to manipulate file system path names (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).
