RHBA-2014:1237 - Bug Fix Advisory

Topic

Updated sssd packages that fix one bug are now available for Red Hat Enterprise
Linux 5.

Description

The System Security Services Daemon (SSSD) provides a set of daemons to manage
access to remote directories and authentication mechanisms. It provides the Name
Service Switch (NSS) and the Pluggable Authentication Modules (PAM) interfaces
toward the system and a pluggable back-end system to connect to multiple
different account sources.

This update fixes the following bug:

• Prior to this update, when a dynamic Domain Name System (DNS) update operation

timed out, it unintentionally freed specific data related to the update.
Consequently, a child_handler() call attempted to access this data, which caused
the sssd_be process to terminate unexpectedly with a segmentation fault. With
this update, child_handler() is destroyed when a dynamic DNS update times out
and sssd_be thus no longer crashes in the described scenario. (BZ#1000205)

Users of sssd are advised to upgrade to these updated packages, which fix this
bug.

Solution

Before applying this update, make sure all previously released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
