Description
qemu, qemu-kvm vulnerabilities Jason Wang discovered that QEMU incorrectly handled the virtio-net device. A remote attacker could use this issue to cause guest network consumption, resulting in a denial of service. (CVE-2015-7295) Qinghao Tang and Ling Liu discovered that QEMU incorrectly handled the pcnet driver when used in loopback mode. 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. (CVE-2015-7504) Ling Liu and Jason Wang discovered that QEMU incorrectly handled the pcnet driver. A remote attacker 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.

USN-3047-2ubuntuqemuqemu, qemu-kvm regression
USN-3047-1 fixed vulnerabilities in QEMU. The patch to fix CVE-2016-5403
caused a regression which resulted in save/restore failures when virtio
memory balloon statistics are enabled. This update temporarily reverts the
security fix for CVE-2016-5403 pending further investigation. We apologize
for the inconvenience.
