The remote host is affected by the vulnerability described in GLSA-201309-24 (Xen: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Xen. Please review the       CVE identifiers referenced below for details.
  Impact :

    Guest domains could possibly gain privileges, execute arbitrary code, or       cause a Denial of Service on the host domain (Dom0). Additionally, guest       domains could gain information about other virtual machines running on       the same host or read arbitrary files on the host.
  Workaround :

    The CVEs listed below do not currently have fixes, but only apply to Xen       setups which have &ldquo;tmem&rdquo; specified on the hypervisor command line.
      TMEM is not currently supported for use in production systems, and       administrators using tmem should disable it.
      Relevant CVEs:
      * CVE-2012-2497
      * CVE-2012-6030
      * CVE-2012-6031
      * CVE-2012-6032
      * CVE-2012-6033
      * CVE-2012-6034
      * CVE-2012-6035
      * CVE-2012-6036
