kde4libs - security update

Sebastian Krahmer discovered that Kauth used Policykit insecurely by
relying on the process ID. This could result in privilege escalation.

For the stable distribution (wheezy), this problem has been fixed in
version 4:4.8.4-4+deb7u1.

For the testing distribution (jessie), this problem has been fixed in
version 4:4.13.3-2.

For the unstable distribution (sid), this problem has been fixed in
version 4:4.13.3-2.

We recommend that you upgrade your kde4libs packages.
