Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated sssd packages that fix one security issue, several bugs, and
add various enhancements are now available for Red Hat Enterprise
Linux 5.

The Red Hat Security Response Team has rated this update as having low
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

The System Security Services Daemon (SSSD) provides a set of daemons
to manage access to remote directories and authentication mechanisms.
It provides an NSS and PAM interface toward the system and a pluggable
back-end system to connect to multiple different account sources. It
is also the basis to provide client auditing and policy services for
projects such as FreeIPA.

A flaw was found in the SSSD PAM responder that could allow a local
attacker to force SSSD to enter an infinite loop via a
carefully-crafted packet. With SSSD unresponsive, legitimate users
could be denied the ability to log in to the system. (CVE-2010-4341)
