high Nessus Plugin ID 110602

Language:

Synopsis

The remote Red Hat host is missing a security update for sssd / ding-libs.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:1877 advisory.

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).

Security Fix(es):

* sssd: unsanitized input when searching in local cache database (CVE-2017-12173)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

This issue was discovered by Sumit Bose (Red Hat).

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL sssd / ding-libs packages based on the guidance in RHSA-2018:1877.
