Test ID:1.3.6.1.4.1.25623.1.0.870857
Category:Red Hat Local Security Checks
Title:RedHat Update for kdelibs RHSA-2012:1416-01
Summary:The remote host is missing an update for the 'kdelibs'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'kdelibs'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
kdelibs on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
