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.

On x86 platforms, the do_insn_fetch() function did not limit the amount of
instruction bytes fetched per instruction. Users in guest operating systems
could leverage this flaw to cause large latencies on SMP hosts that could
lead to a local denial of service on the host operating system. This
update fixes this issue by imposing the architecturally-defined 15 byte
length limit for instructions. (CVE-2009-4031)

All KVM users should upgrade to these updated packages, which contain
backported patches to resolve these issues. Note: The procedure in the");
