Scientific Linux SL5.x Moderate: KVM Security Update CVE-2011-4347

Sender: Security Errata for Scientific Linux From: This email address is being protected from spambots. You need JavaScript enabled to view it. Subject: Security ERRATA Moderate: kvm on SL5.x x86_64 Comments: To: This email address is being protected from spambots. You need JavaScript enabled to view it. Synopsis: Moderate: kvm security and bug fix update Issue Date: 2012-02-21 CVE Numbers: CVE-2011-4347 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. 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.
