New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionKVM (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.
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)
All KVM users should upgrade to these updated packages, which contain backported patches to correct these issues.
SolutionUpdate the affected packages.
