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.
