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.
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.
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
