Scientific Linux Security Update : sssd on SL5.x i386/x86_64
Low Nessus Plugin ID 61094
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionThe 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)
These updated sssd packages include a number of bug fixes and enhancements. Space precludes documenting all of these changes in this advisory.
All sssd users are advised to upgrade to these updated sssd 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.
SolutionUpdate the affected sssd, sssd-client and / or sssd-tools packages.
