Synopsis: Critical: kdelibs security update

Advisory ID: RHSA-2012:1416-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1416.html

Issue date: 2012-10-30

CVE Names: CVE-2012-4512 CVE-2012-4513

=====================================================================

 

1. Summary:

 

Updated kdelibs packages that fix two security issues are now available for

Red Hat Enterprise Linux 6.

 

The Red Hat Security Response Team has rated this update as having critical

security impact. Common Vulnerability Scoring System (CVSS) base scores,

which give detailed severity ratings, are available for each vulnerability

from the CVE links in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64

Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64

Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64

Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64

Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64

 

3. Description:

 

The kdelibs packages provide libraries for the K Desktop Environment

(KDE). Konqueror is a web browser.

 

A heap-based buffer overflow flaw was found in the way the CSS (Cascading

Style Sheets) parser in kdelibs parsed the location of the source for font

faces. A web page containing malicious content could cause an application

using kdelibs (such as Konqueror) to crash or, potentially, execute

arbitrary code with the privileges of the user running the application.

(CVE-2012-4512)

 

A heap-based buffer over-read flaw was found in the way kdelibs calculated

canvas dimensions for large images. A web page containing malicious content

could cause an application using kdelibs to crash or disclose portions of

its memory. (CVE-2012-4513)

 

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 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

https://access.redhat.com/knowledge/articles/11258

 

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

 

865741 - CVE-2012-4513 kdelibs: Heap-based buffer over-read when calculating dimensions of the canvas within the scale loop

865779 - CVE-2012-4512 kdelibs: Heap-based buffer overflow when parsing location of a font face source
