libsmbclient, samba security update

CentOS Errata and Security Advisory CESA-2010:0697

Samba is a suite of programs used by machines to share files, printers, and
other information.

A missing array boundary checking flaw was found in the way Samba parsed
the binary representation of Windows security identifiers (SIDs). A
malicious client could send a specially-crafted SMB request to the Samba
server, resulting in arbitrary code execution with the privileges of the
Samba server (smbd). (CVE-2010-3069)

For Red Hat Enterprise Linux 4, this update also fixes the following bug:

• Previously, the restorecon utility was required during the installation
  of the samba-common package. As a result, attempting to update samba
  without this utility installed may have failed with the following error:

/var/tmp/rpm-tmp.[xxxxx]: line 7: restorecon: command not found

With this update, the utility is only used when it is already present on
the system, and the package is now always updated as expected. (BZ#629602)

Users of Samba are advised to upgrade to these updated packages, which
correct these issues. After installing this update, the smb service will be
restarted automatically.
