  This update fixes the following security issues:

  * A flaw in the dccp_rcv_state_process() function could allow a remote
  attacker to cause a denial of service, even when the socket was already
  closed. (CVE-2011-1093, Important)

  * Multiple buffer overflow flaws were found in the Linux kernel's
  Management Module Support for Message Passing Technology (MPT) based
  controllers. A local, unprivileged user could use these flaws to cause a
  denial of service, an information leak, or escalate their privileges.
  (CVE-2011-1494, CVE-2011-1495, Important)

  * A missing validation of a null-terminated string data structure element
  in the bnep_sock_ioctl() function could allow a local user to cause an
  information leak or a denial of service. (CVE-2011-1079, Moderate)

  * Missing error checking in the way page tables were handled in the Xen
  hypervisor implementation could allow a privileged guest user to cause the
  host, and the guests, to lock up. (CVE-2011-1166, Moderate)

  * A flaw was found in the way the Xen hypervisor implementation checked for
  the upper boundary when getting a new event channel port. A privileged
  guest user could use this flaw to cause a denial of service or escalate
  their privileges. (CVE-2011-1763, Moderate)

  * The start_code and end_code values in '/proc/[pid]/stat' were not
  protected. In certain scenarios, this flaw could be used to defeat Address
  Space Layout Randomization (ASLR). (CVE-2011-0726, Low)

  * A missing initialization flaw in the sco_sock_getsockopt() function could
  allow a local, unprivileged user to cause an information leak.
  (CVE-2011-1078, Low)

  * A missing validation of a null-terminated string data structure element
  in the do_replace() function could allow a local user who has the
  CAP_NET_ADMIN capability to cause an information leak. (CVE-2011-1080, Low)

  * A buffer overflow flaw in the DEC Alpha OSF partition implementation in
  the Linux kernel could allow a local attacker to cause an information leak
  by mounting a disk that contains specially-crafted partition tables.
  (CVE-2011-1163, Low)

  * Missing validations of null-terminated string data structure elements in
  the do_replace(), compat_do_replace(), do_ipt_get_ctl(), do_ip6t_get_ctl(),
  and do_arpt_get_ctl() functions could allow a local user who has the
  CAP_NET_ADMIN capability to cause an information leak. (CVE-2011-1170,
  CVE-2011-1171, CVE-2011-1172, Low)

  * A heap overflow flaw in the Linux kernel's EFI GUID Partition ...
