  script_tag(name:"insight", value:"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 Red Hat Enterprise Linux kernel.

  The kvm_emulate_hypercall() implementation was missing a check for the
  Current Privilege Level (CPL). A local, unprivileged user in a virtual
  machine could use this flaw to cause a local denial of service or escalate
  their privileges within that virtual machine. (CVE-2009-3290)

  This update also fixes the following bugs:

  * non-maskable interrupts (NMI) were not supported on systems with AMD
  processors. As a consequence, Windows Server 2008 R2 guests running with
  more than one virtual CPU assigned on systems with AMD processors would
  hang at the Windows shut down screen when a restart was attempted. This
  update adds support for NMI filtering on systems with AMD processors,
  allowing clean restarts of Windows Server 2008 R2 guests running with
  multiple virtual CPUs. (BZ#520694)

  * significant performance issues for guests running 64-bit editions of
  Windows. This update improves performance for guests running 64-bit
  editions of Windows. (BZ#521793)

  * Windows guests may have experienced time drift. (BZ#521794)

  * removing the Red Hat VirtIO Ethernet Adapter from a guest running Windows
  Server 2008 R2 caused KVM to crash. With this update, device removal should
  not cause this issue. (BZ#524557)

  All KVM users should upgrade to these updated packages, which contain
  backported patches to resolve these issues. Note: The procedure in the
  Solution section must be performed before this update takes effect.");
