RHBA-2011:1143 - sssd bug fix update

Synopsis

sssd bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated sssd packages that resolve an issue are now available for Red Hat Enterprise Linux 6.

Description

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.

These updated sssd packages fix the following bug:

  • Previously, SSSD did not properly close its PAM sockets after an authentication attempt, which eventually resulted in process resource exhaustion and a denial of service situation. The code has been modified to fix this issue, and file descriptors are now properly released when they are no longer in use. (BZ#727041)

All users of sssd are advised to upgrade to these updated packages, which resolve this issue.

Solution

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