Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

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.

A heap overflow flaw was found in the way QEMU-KVM emulated the e1000
network interface card. A privileged guest user in a virtual machine
whose network interface is configured to use the e1000 emulated driver
could use this flaw to crash the host or, possibly, escalate their
privileges on the host. (CVE-2012-0029)

A flaw was found in the way the KVM subsystem of a Linux kernel
handled PIT (Programmable Interval Timer) IRQs (interrupt requests)
when there was no virtual interrupt controller set up. A malicious
user in the kvm group on the host could force this situation to occur,
resulting in the host crashing. (CVE-2011-4622)

All KVM users should upgrade to these updated packages, which contain
backported patches to correct these issues. Note: The procedure in the
Solution section must be performed before this update will take
