Liebe Kolleginnen und Kollegen,

soeben erreichte uns nachfolgendes RedHat Security Advisory. Wir geben
diese Informationen unveraendert an Sie weiter.

CVE-2009-3546 – Buffer Overflow in der Funktion _gdGetColors() der GD
Grafikbibliothek

In der Funktion _gdGetColors() der GD Grafikbibliothek werden
bestimmte Werte n der “colorsTotal” Datenstruktur nicht ausreichend
ueberprueft, so dass ueber die Grenzen eines Arrays hinaus gelesen bzw.
geschrieben werden kann. Ein Angreifer kann diese Schwachstelle dazu
ausnutzen, beliebigen Code mit den Rechten des Benutzers der Anwendung
auszufuehren, welche die Bibliothek verwendet.

Die Schwachstelle ist aehnlich zu, aber nicht identisch mit CVE-2009-3293.

Red Hat Security Advisory

Synopsis: Moderate: gd security update
Advisory ID: RHSA-2010:0003-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0003.html
Issue date: 2010-01-04
CVE Names: CVE-2009-3546
=====================================================================

1. Summary:

Updated gd packages that fix a security issue are now available for Red Hat
Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

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 AS version 4 – i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) – i386, x86_64
Red Hat Enterprise Linux Desktop version 4 – i386, x86_64
Red Hat Enterprise Linux ES version 4 – i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 – i386, ia64, x86_64

3. Description:

The gd packages provide a graphics library used for the dynamic creation of
images, such as PNG and JPEG.

A missing input sanitization flaw, leading to a buffer overflow, was
discovered in the gd library. A specially-crafted GD image file could cause
an application using the gd library to crash or, possibly, execute
arbitrary code when opened. (CVE-2009-3546)

Users of gd should upgrade to these updated packages, which contain a
backported patch to resolve this issue.

4. Solution:

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

This update is available via 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/):

529213 – CVE-2009-3546 gd: insufficient input validation in _gdGetColors()
