RHEA-2011:1810 - sssd bug fix update

Synopsis

sssd bug fix update

Type/Severity

Product Enhancement Advisory

Topic

Updated sssd packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

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

This update fixes the following bugs:

  • SSSD responders did not verify whether a username string, which was passed to SSSD by a client application, contained any invalid UTF-8 characters. As a consequence, SSSD terminated unexpectedly when trying to pass such a string to the data provider over the D-Bus protocol, and the validation test performed by the libdbus library failed. To prevent this problem from occurring, UTF-8 validity checks on the string have been added in the underlying SSSD code. SSSD now does not accept username strings that are not compliant with UTF-8 encoding so that SSSD no longer crashes. (BZ#758696)

  • When establishing a connection to an LDAP server, SSSD did not handle all possible error codes it could receive but only the ETIMEDOUT error code. Therefore, if SSSD received an error code different from ETIMEDOUT, it did not perform the expected failover to another LDAP server and switched to off-line mode. With this update, SSSD has been modified to handle all error codes received on connection attempt. SSSD now tries to connect to all specified LDAP servers and goes off-line only when it fails to connect to all of them. (BZ#758713)

All users of sssd are advised to upgrade to these updated packages, which fix these bugs.

Solution

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