   An update that solves 20 vulnerabilities and has 43 fixes
   is now available.

Description:

   The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:
   - CVE-2016-5829: Multiple heap-based buffer overflows in the
     hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux
     kernel allowed local users to cause a denial of service or possibly have
     unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2)
     HIDIOCSUSAGES ioctl call (bnc#986572).
   - CVE-2016-4997: The compat IPT_SO_SET_REPLACE setsockopt implementation
     in the netfilter subsystem in the Linux kernel allowed local users to
     gain privileges or cause a denial of service (memory corruption) by
     leveraging in-container root access to provide a crafted offset value
     that triggers an unintended decrement (bnc#986362).
   - CVE-2016-4470: The key_reject_and_link function in security/keys/key.c
     in the Linux kernel did not ensure that a certain data structure is
     initialized, which allowed local users to cause a denial of service
     (system crash) via vectors involving a crafted keyctl request2 command
     (bnc#984755).
   - CVE-2016-5244: The rds_inc_info_copy function in net/rds/recv.c in the
     Linux kernel did not initialize a certain structure member, which
     allowed remote attackers to obtain sensitive information from kernel
     stack memory by reading an RDS message (bnc#983213).
   - CVE-2016-1583: The ecryptfs_privileged_open function in
     fs/ecryptfs/kthread.c in the Linux kernel allowed local users to gain
     privileges or cause a denial of service (stack memory consumption) via
     vectors involving crafted mmap calls for /proc pathnames, leading to
     recursive pagefault handling (bnc#983143).
   - CVE-2016-4913: The get_rock_ridge_filename function in fs/isofs/rock.c
     in the Linux kernel mishandled NM (aka alternate name) entries
     containing \0 characters, which allowed local users to obtain sensitive
     information from kernel memory or possibly have unspecified other impact
     via a crafted isofs filesystem (bnc#980725).
   - CVE-2016-4580: The x25_negotiate_facilities function in
     net/x25/x25_facilities.c in the Linux kernel did not properly initialize
     a certain data structure, which allowed attackers to obtain sensitive
     information from kernel stack memory via an X.25 Call Request
     (bnc#981267).
   - CVE-2016-4805: Use-after-free vulnerability in
     drivers/net/ppp/ppp_generic.c in the Linux kernel allowed local users to
     cause a denial of service (memory corruption and system crash, or
     spinlock) or possibly have unspecified other impact by removing a
     network namespace, related to the ppp_register_net_channel and
     ppp_unregister_channel functions (bnc#980371).
   - CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux
     kernel allowed local users to gain privileges via crafted ASN.1 data
     (bnc#979867).
   - CVE-2015-7833: The usbvision driver in the Linux kernel allowed
     physically proximate attackers to cause a denial of service (panic) via
     a nonzero bInterfaceNumber value in a USB device descriptor (bnc#950998).
   - CVE-2016-3707: The icmp_check_sysrq function in net/ipv4/icmp.c in the
     kernel.org projects/rt patches for the Linux kernel, allowed remote
     attackers to execute SysRq commands via crafted ICMP Echo Request
     packets, as demonstrated by a brute-force attack to discover a cookie,
     or an attack that occurs after reading the local icmp_echo_sysrq file
     (bnc#980246).
   - CVE-2016-2187: The gtco_probe function in drivers/input/tablet/gtco.c in
     the Linux kernel allowed physically proximate attackers to cause a
     denial of service (NULL pointer dereference and system crash) via a
     crafted endpoints value in a USB device descriptor (bnc#971944).
   - CVE-2016-4482: The proc_connectinfo function in drivers/usb/core/devio.c
     in the Linux kernel did not initialize a certain data structure, which
     allowed local users to obtain sensitive information from kernel stack
     memory via a crafted USBDEVFS_CONNECTINFO ioctl call (bnc#978401).
   - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in
     the Linux kernel allowed attackers to cause a denial of service (panic)
     via an ASN.1 BER file that lacks a public key, leading to mishandling by
     the public_key_verify_signature function in
     crypto/asymmetric_keys/public_key.c (bnc#963762).
   - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel
     incorrectly relied on the write system call, which allowed local users
     to cause a denial of service (kernel memory write operation) or possibly
     have unspecified other impact via a uAPI interface (bnc#979548).
   - CVE-2016-4485: The llc_cmsg_rcv function in net/llc/af_llc.c in the
     Linux kernel did not initialize a certain data structure, which allowed
     attackers to obtain sensitive information from kernel stack memory by
     reading a message (bnc#978821).
   - CVE-2016-4578: sound/core/timer.c in the Linux kernel did not initialize
     certain r1 data structures, which allowed local users to obtain
     sensitive information from kernel stack memory via crafted use of the
     ALSA timer interface, related to the (1) snd_timer_user_ccallback and
     (2) snd_timer_user_tinterrupt functions (bnc#979879).
   - CVE-2016-4569: The snd_timer_user_params function in sound/core/timer.c
     in the Linux kernel did not initialize a certain data structure, which
     allowed local users to obtain sensitive information from kernel stack
     memory via crafted use of the ALSA timer interface (bnc#979213).
   - CVE-2016-4486: The rtnl_fill_link_ifmap function in net/core/rtnetlink.c
     in the Linux kernel did not initialize a certain data structure, which
     allowed local users to obtain sensitive information from kernel stack
     memory by reading a Netlink message (bnc#978822).
   - CVE-2016-3134: The netfilter subsystem in the Linux kernel did not
     validate certain offset fields, which allowed local users to gain
     privileges or cause a denial of service (heap memory corruption) via an
     IPT_SO_SET_REPLACE setsockopt call (bnc#971126).
