Synopsis: Important: kvm security update
Advisory ID: SLSA-2015:1925-1
Issue Date: 2015-10-22
CVE Numbers: CVE-2015-5279
—
A heap buffer overflow flaw was found in the way QEMU’s NE2000 NIC
emulation implementation handled certain packets received over the
network. A privileged user inside a guest could use this flaw to crash the
QEMU instance (denial of service) or potentially execute arbitrary code on
the host. (CVE-2015-5279)
NOTE: The following procedure must be performed before this update will take
effect:
1) Stop all KVM guest virtual machines.
2) Either reboot the hypervisor machine or, as the root user, remove (using
“modprobe -r [module]”) and reload (using “modprobe [module]”) all of the
following modules which are currently running (determined using “lsmod”):
kvm, ksm, kvm-intel or kvm-amd.
3) Restart the KVM guest virtual machines.
