RHSA-2012:1418 - Critical: kdelibs security update

Synopsis

Critical: kdelibs security update

Type/Severity

Security Advisory Critical

Topic

Updated kdelibs packages that fix two security issues are now available for Red Hat Enterprise Linux 6 FasTrack.

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.

[Updated 21st February 2013] Packages previously available in this erratum were moved to RHBA-2013:0553 to prevent this erratum from incorrectly showing as a security update to users that do not enable FasTrack channels and who had previously received these security fixes via RHSA-2012:1416.

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.

Solution

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