Synopsis:    Moderate: kvm security and bug fix update
Issue Date:  2012-02-21
CVE Numbers: CVE-2011-4347


KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for
the standard Scientific Linux kernel.

It was found that the kvm_vm_ioctl_assign_device() function in the KVM
subsystem of a Linux kernel did not check if the user requesting device
assignment was privileged or not. A member of the kvm group on the host
could assign unused PCI devices, or even devices that were in use and
whose resources were not properly claimed by the respective drivers, which
could result in the host crashing. (CVE-2011-4347)

All KVM users should upgrade to these updated packages, which contain
backported patches to correct these issues.
