The remote Scientific Linux host is missing one or more security
A divide-by-zero flaw was found in the apic_get_tmcct() function in
KVM's Local Advanced Programmable Interrupt Controller (LAPIC)
implementation. A privileged guest user could use this flaw to crash
the host. (CVE-2013-6367)
A memory corruption flaw was discovered in the way KVM handled virtual
APIC accesses that crossed a page boundary. A local, unprivileged user
could use this flaw to crash the system or, potentially, escalate
their privileges on the system. (CVE-2013-6368)
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.
