tag_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.";
