hypervisor.

  - CVE-2011-1166
    A 64-bit guest can get one of its vCPUs into non-kernel
    mode without first providing a valid non-kernel
    pagetable, thereby locking up the host system.

  - CVE-2011-1583, CVE-2011-3262
    Local users can cause a denial of service and possibly
    execute arbitrary code via a crafted paravirtualised
    guest kernel image.

  - CVE-2011-1898
    When using PCI passthrough on Intel VT-d chipsets that
    do not have interrupt remapping, guest OS users can gain
    host OS privileges by writing to the interrupt injection
    registers.

The oldstable distribution (lenny) contains a different version of Xen
not affected by these problems."

(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 “tmem” 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
