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 moderate 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).

A cross-site scripting (XSS) flaw was found in the way KHTML, the HTML layout engine used by KDE applications such as the Konqueror web browser, displayed certain error pages. A remote attacker could use this flaw to perform a cross-site scripting attack against victims by tricking them into visiting a specially crafted URL. (CVE-2011-1168)

A flaw was found in the way kdelibs checked the user specified hostname against the name in the server’s SSL certificate. A man-in-the-middle attacker could use this flaw to trick an application using kdelibs into mistakenly accepting a certificate as if it was valid for the host, if that certificate was issued for an IP address to which the user specified hostname was resolved to. (CVE-2011-1094)

Note: As part of the fix for CVE-2011-1094, this update also introduces stricter handling for wildcards used in servers’ SSL certificates.

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.
