Calendar Grey April 21, 2011
Dist Redhat Esm H88
New kdelibs updates released for Red Hat Enterprise Linux 6 addressing two security vulnerabilities, classified as moderate risk.
Updated kdelibs packages that fix two security issues are now available for Red Hat Enterprise Linux 6

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/kb/docs/DOC-11259

Summary

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.
