   An update that solves 11 vulnerabilities and has two fixes
   is now available. It includes one version update.

Description:

   The openSUSE 11.3 kernel was updated to fix various bugs
   and security issues.

   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   to read kernel memory.

   CVE-2011-2203: A NULL ptr dereference on mounting corrupt
   hfs filesystems was fixed which could be used by local
   attackers to crash the kernel.

   CVE-2011-4081: Using the crypto interface a local user
   could Oops the kernel by writing to a AF_ALG socket.
