Title:	RedHat Security Advisory RHSA-2011:0028
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory RHSA-2011:0028. 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 data structure field in kvm_vcpu_ioctl_x86_get_vcpu_events() in QEMU-KVM was 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-2010-4525) Red Hat would like to thank Stephan Mueller of atsec information security for reporting this issue. These updated packages also fix several bugs. Documentation for these bug fixes will be available shortly in the kvm section of the Red Hat Enterprise Linux 5.6 Technical Notes, linked to in the References. All KVM users should upgrade to these updated packages, which resolve this issue as well as fixing the bugs noted in the Technical Notes. 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-2011-0028.html http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/5.6_Technical_Notes/index.html Risk factor : Low CVSS Score: 1.9
