Title:RedHat Update for sssd RHSA-2011:0560-01
Summary:The remote host is missing an update for the 'sssd'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'sssd'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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 crash SSSD via a carefully-crafted packet. With SSSD
unresponsive, legitimate users could be denied the ability to log in to the
system. (CVE-2010-4341)

Red Hat would like to thank Sebastian Krahmer for reporting this issue.

This update also fixes several bugs and adds various enhancements.
Documentation for these bug fixes and enhancements will be available
shortly from the Technical Notes document, linked to in the References

Users of SSSD should upgrade to these updated packages, which upgrade SSSD
to upstream version 1.5.1 to correct this issue, and fix the bugs and add
the enhancements noted in the Technical Notes.

Affected Software/OS:
sssd on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Please Install the Updated Packages.
