The kdelibs and kdelibs3 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. Users should upgrade to these updated packages, which contain a backported patch to correct this issue. The desktop must be restarted for this update to take effect.
