  script_tag(name:"insight", value:"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 ... [Please see the references for more information on the vulnerabilities]");
