  script_tag(name:"insight", value:"The openSUSE 11.3 kernel was updated to fix various bugs
  and security issues.

  The following security issues have been fixed: CVE-2011-4604:
  If root does read() on a specific socket, it's possible to
  corrupt (kernel) memory over network, with an ICMP packet,
  if the B.A.T.M.A.N. mesh protocol is used.

  CVE-2011-2525: A flaw allowed the tc_fill_qdisc() function
  in the Linux kernels packet scheduler API implementation to
  be called on built-in qdisc structures. A local,
  unprivileged user could have used this flaw to trigger a
  NULL pointer dereference, resulting in a denial of service.

  CVE-2011-2699: Fernando Gont discovered that the IPv6 stack
  used predictable fragment identification numbers. A remote
  attacker could exploit this to exhaust network resources,
  leading to a denial of service.

  CVE-2011-2213: The inet_diag_bc_audit function in
  net/ipv4/inet_diag.c in the Linux kernel did not properly
  audit INET_DIAG bytecode, which allowed local users to
  cause a denial of service (kernel infinite loop) via
  crafted INET_DIAG_REQ_BYTECODE instructions in a netlink
  message, as demonstrated by an INET_DIAG_BC_JMP instruction
  with a zero yes value, a different vulnerability than
  CVE-2010-3880.

  CVE-2011-1576: The Generic Receive Offload (GRO)
  implementation in the Linux kernel allowed remote attackers
  to cause a denial of service via crafted VLAN packets that
  are processed by the napi_reuse_skb function, leading to
  (1) a memory leak or (2) memory corruption, a different
  vulnerability than CVE-2011-1478.

  CVE-2011-2534: Buffer overflow in the clusterip_proc_write
  function in net/ipv4/netfilter/ipt_CLUSTERIP.c in the Linux
  kernel might have allowed local users to cause a denial of
  service or have unspecified other impact via a crafted
  write operation, related to string data that lacks a
  terminating '\0' character.

  CVE-2011-1770: Integer underflow in the dccp_parse_options
  function (net/dccp/options.c) in the Linux kernel allowed
  remote attackers to cause a denial of service via a
  Datagram Congestion Control Protocol (DCCP) packet with an
  invalid feature options length, which triggered a buffer
  over-read.

  CVE-2011-2723: The skb_gro_header_slow function in
  include/linux/netdevice.h in the Linux kernel, when Generic
  Receive Offload (GRO) is enabled, reset certain fields in
  incorrect situations, which allowed remote attackers to
  cause a denial of service (system crash) via crafted
  network traffic.

  CVE-2011-2898: A kernel information leak in the AF_PACKET
  protocol was fixed which might have allowed local attackers
