(Red Hat Issues Fix for kdegraphics) Apple Safari Bugs Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1022460
SecurityTracker URL:  http://securitytracker.com/id/1022460
CVE Reference:   CVE-2009-1709   (Links to External Site)
Date:  Jun 26 2009
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Several vulnerabilities were reported in Apple Safari. A remote user can cause arbitrary code to be executed on the target user's system. Kdegraphics is affected by one vulnerability.

A remote user can create specially crafted content that, when loaded by the target user, will execute arbitrary code on the target system. The code will run with the privileges of the target user.

Specially crafted JavaScript can trigger a flaw in JavaScript exception handling [CVE-2009-1686]. Jesse Ruderman of Mozilla Corporation reported this vulnerability.

Specially crafted JavaScript can trigger a memory corruption error in WebKit's JavaScript garbage collector [CVE-2009-1687]. SkyLined of Google Inc. reported this vulnerability.

Specially crafted HTML can trigger a memory corruption error in WebKit's processing of certain DOM event handlers [CVE-2009-1690]. SkyLined of Google Inc. and wushi & ling of team509 (via iDefense) reported this vulnerability.

Specially crafted CSS code can trigger an uninitialized pointer bug in the processing of the CSS 'attr' function [CVE-2009-1698]. Thierry Zoller (via TippingPoint) and Robert Swiecki of the Google Security Team reported this vulnerability.

Specially crafted HTML can trigger a use-after-free bug in the processing of the JavaScript DOM [CVE-2009-1701]. wushi & ling of team509 (via TippingPoint) reported this vulnerability.

A bug in the open-help-anchor URL handler may let remote users access local files or execute arbitrary code [CVE-2009-1708]. Billy Rios and Microsoft Vulnerability Research reported this vulnerability.

Specially crafted SVN animation elements can trigger a use-after-free bug [CVE-2009-1709]. An anonymous researcher (via TippingPoint) reported this vulnerability.

Specially crafted HTML can trigger an uninitialized memory access bug in the processing of Attr DOM objects [CVE-2009-1711]. Feng Qian of Google Inc. reported this vulnerability.

A remote web site can load local applets, which may let remote users access potentially sensitive information or execute arbitrary code [CVE-2009-1712].

Impact:   A remote user can create HTML or other content that, when loaded by the target user, will execute arbitrary code on the target user's system.
Solution:   Red Hat has released a fix for kdegraphics, which is affected by CVE-2009-1709.

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

=====================================================================
                   Red Hat Security Advisory

Synopsis:          Critical: kdegraphics security update
Advisory ID:       RHSA-2009:1130-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2009-1130.html
Issue date:        2009-06-25
CVE Names:         CVE-2009-0945 CVE-2009-1709 
=====================================================================

1. Summary:

Updated kdegraphics packages that fix two security issues are now available
for Red Hat Enterprise Linux 5.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64

3. Description:

The kdegraphics packages contain applications for the K Desktop Environment
(KDE). Scalable Vector Graphics (SVG) is an XML-based language to describe
vector images. KSVG is a framework aimed at implementing the latest W3C SVG
specifications.

A use-after-free flaw was found in the KDE KSVG animation element
implementation. A remote attacker could create a specially-crafted SVG
image, which once opened by an unsuspecting user, could cause a denial of
service (Konqueror crash) or, potentially, execute arbitrary code with the
privileges of the user running Konqueror. (CVE-2009-1709)

A NULL pointer dereference flaw was found in the KDE, KSVG SVGList
interface implementation. A remote attacker could create a
specially-crafted SVG image, which once opened by an unsuspecting user,
would cause memory corruption, leading to a denial of service (Konqueror
crash). (CVE-2009-0945)

All users of kdegraphics should upgrade to these updated packages, which
contain backported patches to correct these issues. The desktop must be
restarted (log out, then log back in) for this update to take effect.

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/):

506246 - CVE-2009-1709 kdegraphics: KSVG Pointer use-after-free error in the SVG animation element (DoS, ACE)
506703 - CVE-2009-0945 kdegraphics: KSVG NULL-pointer dereference in the SVGList interface implementation (ACE)
