3. Description:

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)

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

4. 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
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

630869 - CVE-2010-3069 Samba: Stack-based buffer overflow by processing
 specially-crafted SID records
