diese Informationen unveraendert an Sie weiter.

CVE-2010-3069 – Schwachstelle im Samba Dateiserver

Der Samba Dateiserver verarbeitet sog. Security Identifiers (SID)
fehlerhaft, was zu einem Buffer Overflow fuehren kann. Ein entfernter,
nicht angemeldeter Benutzer kann diese Schwachstelle mit Hilfe
speziell vorbereiteter SIDs ausnutzen um einen Absturz des Servers
auszuloesen oder beliebige Befehle im Rechtekontext des Samba Servers
smbd auszufuehren.

Betroffen sind die folgenden Software Pakete und Plattformen:

Paket samba3x

RHEL Desktop Workstation (v. 5 client) – i386, x86_64
Red Hat Enterprise Linux (v. 5 server) – i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) – i386, x86_64

Vom Hersteller werden ueberarbeitete Pakete zur Verfuegung gestellt.

CVE Names: CVE-2010-3069
=====================================================================

1. Summary:

Updated samba3x packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having critical
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) – i386, x86_64
Red Hat Enterprise Linux (v. 5 server) – i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) – i386, x86_64

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
contain a backported patch to 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/):
