Title:	RedHat Update for xen RHSA-2012:1130-01
Summary:	The remote host is missing an update for the 'xen'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'xen' package(s) announced via the referenced advisory. Vulnerability Insight: The xen packages contain administration tools and the xend service for managing the kernel-xen kernel for virtualization on Red Hat Enterprise Linux. A flaw was found in the way the pyGrub boot loader handled compressed kernel images. A privileged guest user in a para-virtualized guest (a DomU) could use this flaw to create a crafted kernel image that, when attempting to boot it, could result in an out-of-memory condition in the privileged domain (the Dom0). (CVE-2012-2625) Red Hat would like to thank Xinli Niu for reporting this issue. All users of xen are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, the xend service must be restarted for this update to take effect. Affected Software/OS: xen on Red Hat Enterprise Linux (v. 5 server) Solution: Please Install the Updated Packages. CVSS Score: 2.7 CVSS Vector: AV:A/AC:L/Au:S/C:N/I:N/A:P
