This update fixes the following security issues :
* A flaw was found in the way KVM (Kernel-based Virtual Machine)
initialized a guest's registered pv_eoi (paravirtualized

unprivileged guest user could potentially use this flaw to crash the
host. (CVE-2013-1935, Important)
* A missing sanity check was found in the kvm_set_memory_region()
function in KVM, allowing a user-space process to register memory
regions pointing to the kernel address space. A local, unprivileged
user could use this flaw to escalate their privileges. (CVE-2013-1943,

Tunnel driver (veth). A remote attacker could possibly use this flaw
to crash a target system. (CVE-2013-2017, Moderate)
