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.

A flaw was found in the way QEMU-KVM emulated the e1000 network
interface card when the host was configured to accept jumbo network
frames, and a guest using the e1000 emulated driver was not. A remote
attacker could use this flaw to crash the guest or, potentially,
execute arbitrary code with root privileges in the guest.
(CVE-2012-6075)

All users of kvm are advised to upgrade to these updated packages,
which contain backported patches to correct this issue. Note that the
