Red Hat: RHSA-2011:1364-01 Moderate: Kdelibs SSL Certificate Issue

red hat
Calendar Grey October 11, 2011
Dist Redhat Esm H88
Revised kdelibs for Fedora tackles a significant security concern and improves certificate verification.
Updated kdelibs packages that fix one security issue and add one enhancement 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).
An input sanitization flaw was found in the KSSL (KDE SSL Wrapper) API. An attacker could supply a specially-crafted SSL certificate (for example, via a web page) to an application using KSSL, such as the Konqueror web browser, causing misleading information to be presented to the user, possibly tricking them into accepting the certificate as valid. (CVE-2011-3365)
This update also adds the following enhancement:
* kdelibs provided its own set of trusted Certificate Authority (CA) certificates. This update makes kdelibs use the system set from the ca-certificates package, instead of its own copy. (BZ#743951)
Users should upgrade to these updated packages, which contain backported patches to correct this issue and add this enhancement. The desktop must be restarted (log out, then log back in) for this update to take effect.
