add various enhancements are now available for Red Hat Enterprise
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 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
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.
