Synopsis:    Low: sssd security, bug fix, and enhancement update
Issue Date:  2011-05-19
CVE Numbers: CVE-2010-4341


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)

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
section.

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.
