Gentoo Linux Security Advisory 201210-4 - Multiple vulnerabilities were found in qemu-kvm, allowing attackers to execute arbitrary code. Versions less than 1.1.1-r1 are affected.
06a3dcc607829516f85c54a5f5e6c417bc1c799c5779cfc55ea88d07821757e1Red Hat Security Advisory 2012-0370-01 - The xen packages contain administration tools and the xend service for managing the kernel-xen kernel for virtualization on Red Hat Enterprise Linux. A heap overflow flaw was found in the way QEMU emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash QEMU or, possibly, escalate their privileges on the host.

The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. A heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host or, possibly, escalate their privileges on the host.

e1c64876866c54ec12cca4a32694484ec81d3e3006e2a8241ae30bb609a58057Ubuntu Security Notice 1339-1 - Nicolae Mogoreanu discovered that QEMU did not properly verify legacy mode packets in the e1000 network driver. A remote attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program. 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. Various other issues were also addressed.

KVM is a Linux kernel module built for the standard Red Hat Enterprise Linux kernel. A heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host or, possibly, escalate their privileges on the host. A flaw was found in the way the KVM subsystem of a Linux kernel handled PIT IRQs when there was no virtual interrupt controller set up. A malicious user in the kvm group on the host could force this situation to occur, resulting in the host crashing.
