CentOS Update for kvm-83-105.el5_ CESA-2009:1465 centos5 i386
The remote host is missing an update for the 'kvm-83-105.el5_' package(s) announced via the referenced advisory.
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. The kvm_emulate_hypercall() implementation was missing a check for the Current Privilege Level (CPL). A local, unprivileged user in a virtual machine could use this flaw to cause a local denial of service or escalate their privileges within that virtual machine. (CVE-2009-3290) This update also fixes the following bugs: * non-maskable interrupts (NMI) were not supported on systems with AMD processors. As a consequence, Windows Server 2008 R2 guests running with more than one virtual CPU assigned on systems with AMD processors would hang at the Windows shut down screen when a restart was attempted. This update adds support for NMI filtering on systems with AMD processors, allowing clean restarts of Windows Server 2008 R2 guests running with multiple virtual CPUs. (BZ#520694) * significant performance issues for guests running 64-bit editions of Windows. This update improves performance for guests running 64-bit editions of Windows. (BZ#521793) * Windows guests may have experienced time drift. (BZ#521794) * removing the Red Hat VirtIO Ethernet Adapter from a guest running Windows Server 2008 R2 caused KVM to crash. With this update, device removal should not cause this issue. (BZ#524557) All KVM users should upgrade to these updated packages, which contain backported patches to resolve these issues. Note: The procedure in the Solution section must be performed before this update takes effect.
