qemu-kvm - Machine emulator and virtualizer

Details

Nelson Elhage discoverd that QEMU did not properly validate certain
virtqueue requests from the guest. An attacker could exploit this to cause
a denial of service of the guest or possibly execute code with the
privileges of the user invoking the program. (CVE-2011-2212)

Stefan Hajnoczi discovered that QEMU did not properly perform integer
comparisons when performing virtqueue input validation. An attacker could
exploit this to cause a denial of service of the guest or possibly execute
code with the privileges of the user invoking the program. (CVE-2011-2512)

When using QEMU with libvirt or virtualization management software based on
libvirt such as Eucalyptus and OpenStack, QEMU guests are individually
isolated by an AppArmor profile by default in Ubuntu.
