The remote Scientific Linux host is missing one or more security
It was found that KVM's Write to Model Specific Register (WRMSR)
instruction emulation would write non-canonical values passed in by
the guest to certain MSRs in the host's context. A privileged guest
user could use this flaw to crash the host. (CVE-2014-3610)
A race condition flaw was found in the way the Linux kernel's KVM
subsystem handled PIT (Programmable Interval Timer) emulation. A guest
user who has access to the PIT I/O ports could use this flaw to crash
the host. (CVE-2014-3611)
Note: The following procedure must be performed before this update
will take effect :
1) Stop all KVM guest virtual machines.
2) Either reboot the hypervisor machine or, as the root user, remove
(using 'modprobe -r [module]') and reload (using 'modprobe [module]')
all of the following modules which are currently running (determined
using 'lsmod'): kvm, ksm, kvm-intel or kvm-amd.
3) Restart the KVM guest virtual machines.
or you may restart your system.
