kde4libs - security update

It was possible to trick kde4libs’s KArchiveDirectory::copyTo()
function to extract files to arbitrary system locations from
a specially prepared tar file outside of the extraction folder.

For Debian 7 Wheezy, these problems have been fixed in version
4:4.8.4-4+deb7u2.

We recommend that you upgrade your kde4libs packages.
