Title:	RedHat Security Advisory RHSA-2010:0998
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory RHSA-2010:0998. 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 some structure padding and reserved fields in certain data structures in QEMU-KVM were not initialized properly before being copied to user-space. A privileged host user with access to /dev/kvm could use this flaw to leak kernel stack memory to user-space. (CVE-2010-3881) Red Hat would like to thank Vasiliy Kulikov for reporting this issue. 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. Solution: 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 http://rhn.redhat.com/errata/RHSA-2010-0998.html Risk factor : Low CVSS Score: 1.9
