Title:	RedHat Security Advisory RHSA-2012:0149
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory RHSA-2012:0149. 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. It was found that the kvm_vm_ioctl_assign_device() function in the KVM subsystem of a Linux kernel did not check if the user requesting device assignment was privileged or not. A member of the kvm group on the host could assign unused PCI devices, or even devices that were in use and whose resources were not properly claimed by the respective drivers, which could result in the host crashing. (CVE-2011-4347) Red Hat would like to thank Sasha Levin for reporting this issue. These updated kvm packages include several bug fixes. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 5.8 Technical Notes, linked to in the References, for information on the most significant of these changes. 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 effect. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2012-0149.html Risk factor : Medium
