Updated kdelibs packages that fix one security issue and add one enhancement are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System base score, which gives a detailed severity rating, is available from the CVE link in the References section. Description The kdelibs packages provide libraries for the K Desktop Environment . An input sanitization flaw was found in the KSSL API. An attacker could supply a specially-crafted SSL certificate 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. This update also adds the following enhancement: kdelibs provided its own set of trusted Certificate Authority certificates. This update makes kdelibs use the system set from the ca-certificates package, instead of its own copy. Users should upgrade to these updated packages, which contain backported patches to correct this issue and add this enhancement. The desktop must be restarted for this update to take effect.
