An update that solves 25 vulnerabilities and has 22 fixes
is now available.

Description:

The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive
various security and bugfixes.

The following security bugs were fixed:
– CVE-2016-3955: The usbip_recv_xbuff function in
drivers/usb/usbip/usbip_common.c in the Linux kernel allowed remote
attackers to cause a denial of service (out-of-bounds write) or possibly
have unspecified other impact via a crafted length value in a USB/IP
packet (bnc#975945).
– CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt implementation in the
netfilter subsystem in the Linux kernel allowed local users to cause a
denial of service (out-of-bounds read) or possibly obtain sensitive
information from kernel heap memory by leveraging in-container root
access to provide a crafted offset value that leads to crossing a
ruleset blob boundary (bnc#986365).
– CVE-2015-7513: arch/x86/kvm/x86.c in the Linux kernel did not reset the
PIT counter values during state restoration, which allowed guest OS
users to cause a denial of service (divide-by-zero error and host OS
crash) via a zero value, related to the kvm_vm_ioctl_set_pit and
kvm_vm_ioctl_set_pit2 functions (bnc#960689).
– CVE-2013-4312: The Linux kernel allowed local users to bypass
file-descriptor limits and cause a denial of service (memory
consumption) by sending each descriptor over a UNIX socket before
closing it, related to net/unix/af_unix.c and net/unix/garbage.c
(bnc#839104).
– 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-2016-5829: Multiple heap-based buffer overflows in the
hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux
kernel allow 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-2016-4470: The key_reject_and_link function in security/keys/key.c
in the Linux kernel did not ensure that a certain data structure was
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-2016-2187: 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-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel
incorrectly relies 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-2016-2053: 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-2016-4485: 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).
– CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly
determine the rate of challenge ACK segments, which made it easier for
man-in-the-middle attackers to hijack TCP sessions via a blind in-window
attack. (bsc#989152)
– CVE-2016-6480: Race condition in the ioctl_send_fib function in
drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users
to cause a denial of service (out-of-bounds access or system crash) by
changing a certain size value, aka a “double fetch” vulnerability.
