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.
