Detail
Problem Description: Updated kvm packages that fix two security issues are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEL Desktop Multi OS (v. 5 client) - x86_64 RHEL Virtualization (v. 5 server) - x86_64 3. Description: 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 divide-by-zero flaw was found in the apic_get_tmcct() function in KVM's Local Advanced Programmable Interrupt Controller (LAPIC) implementation. A privileged guest user could use this flaw to crash the host. (CVE-2013-6367) A memory corruption flaw was discovered in the way KVM handled virtual APIC accesses that crossed a page boundary. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-6368) Red Hat would like to thank Andrew Honig of Google for reporting these issues. All kvm users are advised to 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 The following procedure must be performed before this update will take effect: 1) Stop all KVM guest virtual machines. 2) Either reboot the hypervisor machine or, as the root user, remove (using "modprobe -r [module]") and reload (using "modprobe [module]") all of the following modules which are currently running (determined using "lsmod"): kvm, ksm, kvm-intel or kvm-amd. 3) Restart the KVM guest virtual machines. 5. Bugs fixed (https://bugzilla.redhat.com/): 1032207 - CVE-2013-6367 kvm: division by zero in apic_get_tmcct() 1032210 - CVE-2013-6368 kvm: cross page vapic_addr access |
