Debian: Security update for qemu-kvm

Two vulnerabilities have been discovered in KVM, a solution for full virtualization on x86 hardware. Nelson Elhage discovered a buffer overflow in the virtio subsystem, which could lead to denial of service or privilege escalation. Andrew Griffiths discovered that group privileges were insufficiently dropped when started with -runas option, resulting in privilege escalation. Updated packages are available from security.debian.org.
