(Red Hat Issues Fix for kdelibs) Apple Safari Bugs Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1022473
SecurityTracker URL:  http://securitytracker.com/id/1022473
CVE Reference:   CVE-2009-1687, CVE-2009-1690, CVE-2009-1698   (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. kdelibs is affected.

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 kdelibs for CVE-2009-1687, CVE-2009-1690, and CVE-2009-1698.

Hash: SHA1

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

Synopsis:          Critical: kdelibs security update
Advisory ID:       RHSA-2009:1127-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2009-1127.html
Issue date:        2009-06-25
CVE Names:         CVE-2009-1687 CVE-2009-1690 CVE-2009-1698 
=====================================================================

1. Summary:

Updated kdelibs packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 4 and 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 AS version 4 - i386, ia64, ppc, s390, s390x, 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
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

The kdelibs packages provide libraries for the K Desktop Environment (KDE).

A flaw was found in the way the KDE CSS parser handled content for the
CSS "style" attribute. A remote attacker could create a specially-crafted
CSS equipped HTML page, which once visited 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-2009-1698)

A flaw was found in the way the KDE HTML parser handled content for the
HTML "head" element. A remote attacker could create a specially-crafted
HTML page, which once visited 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-2009-1690)

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way the KDE JavaScript garbage collector handled memory
allocation requests. A remote attacker could create a specially-crafted
HTML page, which once visited 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-2009-1687)

Users 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/):

505571 - CVE-2009-1690 kdelibs: KHTML Incorrect handling <head> element content once the <head> element was removed (DoS,
 ACE)
506453 - CVE-2009-1687 kdelibs: Integer overflow in KJS JavaScript garbage collector
506469 - CVE-2009-1698 kdelibs: KHTML CSS parser - incorrect handling CSS "style" attribute content (DoS, ACE)
