Synopsis:          Important: kvm security update
Advisory ID:       SLSA-2015:1189-1
Issue Date:        2015-06-25
CVE Numbers:       CVE-2015-3209
--

A flaw was found in the way QEMU's AMD PCnet Ethernet emulation handled
multi-TMD packets with a length above 4096 bytes. A privileged guest user
in a guest with an AMD PCNet ethernet card enabled could potentially use
this flaw to execute arbitrary code on the host with the privileges of the
hosting QEMU process. (CVE-2015-3209)

KVM must be "restarted" before this update will take effect.  

  Shutdown all KVM virtual machines.  

  Either reboot or unload and reload the following kernel modules : kvm, ksm,   kvm-intel or kvm-amd.  

  Start the KVM virtual machines.
