The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM. A heap buffer overflow flaw was found in the way QEMU's IDE subsystem handled I/O buffer access while processing certain ATAPI commands. A privileged guest user in a guest with the CDROM drive enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest.
530e72ca2188050dcc033500673eaf1070ae047e520dfe654e66a7a68f67e08aUbuntu Security Notice 2692-1 - Matt Tait discovered that QEMU incorrectly handled PIT emulation. In a non-default configuration, a malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. Kevin Wolf discovered that QEMU incorrectly handled processing ATAPI commands. A malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the QEMU process. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. Various other issues were also addressed.
