Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2012:0149
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.

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
