"This Linux kernel update fixes various security issues and bugs in the
SUSE Linux Enterprise 10 SP4 kernel.

The following security issues have been fixed :

CVE-2011-2494: kernel/taskstats.c in the Linux kernel allowed local
users to obtain sensitive I/O statistics by sending taskstats commands
to a netlink socket, as demonstrated by discovering the length of
another users password (a side channel attack).

CVE-2012-2744: net/ipv6/netfilter/nf_conntrack_reasm.c in
the Linux kernel, when the nf_conntrack_ipv6 module is
enabled, allowed remote attackers to cause a denial of
service (NULL pointer dereference and system crash) via
certain types of fragmented IPv6 packets.

CVE-2012-3510: Use-after-free vulnerability in the
xacct_add_tsk function in kernel/tsacct.c in the Linux
kernel allowed local users to obtain potentially sensitive
information from kernel memory or cause a denial of service
(system crash) via a taskstats TASKSTATS_CMD_ATTR_PID
command.

CVE-2011-4110: The user_update function in
security/keys/user_defined.c in the Linux kernel 2.6 allowed
local users to cause a denial of service (NULL pointer
dereference and kernel oops) via vectors related to a
user-defined key and updating a negative key into a fully
instantiated key.

CVE-2011-1044: The ib_uverbs_poll_cq function in
drivers/infiniband/core/uverbs_cmd.c in the Linux kernel did
not initialize a certain response buffer, which allowed
local users to obtain potentially sensitive information from
kernel memory via vectors that cause this buffer to be only
partially filled, a different vulnerability than
CVE-2010-4649.

CVE-2012-3400: Heap-based buffer overflow in the
udf_load_logicalvol function in fs/udf/super.c in the Linux
kernel allowed remote attackers to cause a denial of service
(system crash) or possibly have unspecified other impact via
a crafted UDF filesystem.

CVE-2012-2136: The sock_alloc_send_pskb function in
net/core/sock.c in the Linux kernel did not properly
validate a certain length value, which allowed local users
to cause a denial of service (heap-based buffer overflow and
system crash) or possibly gain privileges by leveraging
access to a TUN/TAP device.

CVE-2012-2663: A small denial of service leak in dropping
syn+fin messages was fixed.

The following non-security issues have been fixed :

Packaging :

  - kbuild: Fix gcc -x syntax (bnc#773831).

NFS :

  - knfsd: An assortment of little fixes to the sunrpc cache
    code (bnc#767766).

  - knfsd: Unexport cache_fresh and fix a small race
    (bnc#767766).

  - knfsd: nfsd: do not drop silently on upcall deferral
    (bnc#767766).

  - knfsd: svcrpc: remove another silent drop from deferral
    code (bnc#767766).

  - sunrpc/cache: simplify cache_fresh_locked and
    cache_fresh_unlocked (bnc#767766).

  - sunrpc/cache: recheck cache validity after
    cache_defer_req (bnc#767766).

  - sunrpc/cache: use list_del_init for the list_head
    entries in cache_deferred_req (bnc#767766).

  - sunrpc/cache: avoid variable over-loading in
    cache_defer_req (bnc#767766).

  - sunrpc/cache: allow thread to block while waiting for
    cache update (bnc#767766).

  - sunrpc/cache: Fix race in sunrpc/cache introduced by
    patch to allow thread to block while waiting for cache
    update (bnc#767766).

  - sunrpc/cache: Another fix for race problem with sunrpc
    cache deferal (bnc#767766).

  - knfsd: nfsd: make all exp_finding functions return

-errnos on err (bnc#767766).

  - Fix kabi breakage in previous nfsd patch series
    (bnc#767766).

  - nfsd: Work around incorrect return type for
    wait_for_completion_interruptible_timeout (bnc#767766).

  - nfs: Fix a potential file corruption issue when writing
    (bnc#773272).

  - nfs: Allow sync writes to be multiple pages
    (bnc#763526).

  - nfs: fix reference counting for NFSv4 callback thread
    (bnc#767504).

  - nfs: flush signals before taking down callback thread
    (bnc#767504).

  - nfsv4: Ensure nfs_callback_down() calls svc_destroy()
    (bnc#767504).

  - SCSI/ch: Check NULL for kmalloc() return (bnc#783058).
    drivers/scsi/aic94xx/aic94xx_init.c: correct the size
    argument to kmalloc (bnc#783058).

    block: fail SCSI passthrough ioctls on partition devices
    (bnc#738400).

    dm: do not forward ioctls from logical volumes to the
    underlying device (bnc#738400).

    vmware: Fix VMware hypervisor detection (bnc#777575,
    bnc#770507).

S/390 :

  - lgr: Make lgr_page static (bnc#772409,LTC#83520).
