Description

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.

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.
