Security update for the Linux Kernel (important)

The openSUSE 12.3 kernel was updated to fix security issues:

This will be the final kernel update for openSUSE 13.2 during its
lifetime, which ends January 4th 2015.

CVE-2014-9322: A local privilege escalation in the x86_64 32bit
compatibility signal handling was fixed, which could be used by local
attackers to crash the machine or execute code.

CVE-2014-9090: The do_double_fault function in arch/x86/kernel/traps.c in
the Linux kernel did not properly handle faults associated with the Stack
Segment (SS) segment register, which allowed local users to cause a denial
of service (panic) via a modify_ldt system call, as demonstrated by
sigreturn_32 in the linux-clock-tests test suite.

CVE-2014-8133: Insufficient validation of TLS register usage could leak
information from the kernel stack to userspace.

CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel on 32-bit
x86 platforms, when syscall auditing is enabled and the sep CPU feature
flag is set, allowed local users to cause a denial of service (OOPS and
system crash) via an invalid syscall number, as demonstrated by number
1000.

CVE-2014-8884: Stack-based buffer overflow in the
ttusbdecfe_dvbs_diseqc_send_master_cmd function in
drivers/media/usb/ttusb-dec/ttusbdecfe.c in the Linux kernel allowed local
users to cause a denial of service (system crash) or possibly gain
privileges via a large message length in an ioctl call.

CVE-2014-3186: Buffer overflow in the picolcd_raw_event function in
devices/hid/hid-picolcd_core.c in the PicoLCD HID device driver in the
Linux kernel, as used in Android on Nexus 7 devices, allowed physically
proximate attackers to cause a denial of service (system crash) or
possibly execute arbitrary code via a crafted device that sends a large
report.

CVE-2014-7841: The sctp_process_param function in net/sctp/sm_make_chunk.c
in the SCTP implementation in the Linux kernel, when ASCONF is used,
allowed remote attackers to cause a denial of service (NULL pointer
dereference and system crash) via a malformed INIT chunk.

CVE-2014-4608: Multiple integer overflows in the lzo1x_decompress_safe
function in lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the
Linux kernel allowed context-dependent attackers to cause a denial
of service (memory corruption) via a crafted Literal Run.

CVE-2014-8709: The ieee80211_fragment function in net/mac80211/tx.c in the
Linux kernel did not properly maintain a certain tail pointer, which
allowed remote attackers to obtain sensitive cleartext information by
reading packets.

CVE-2014-3185: Multiple buffer overflows in the command_port_read_callback
function in drivers/usb/serial/whiteheat.c in the Whiteheat USB Serial
Driver in the Linux kernel allowed physically proximate attackers to
execute arbitrary code or cause a denial of service (memory corruption and
system crash) via a crafted device that provides a large amount of (1)
EHCI or (2) XHCI data associated with a bulk response.

CVE-2014-3184: The report_fixup functions in the HID subsystem in the
Linux kernel might have allowed physically proximate attackers to cause a
denial of service (out-of-bounds write) via a crafted device that provides
a small report descriptor, related to (1) drivers/hid/hid-cherry.c, (2)
drivers/hid/hid-kye.c, (3) drivers/hid/hid-lg.c, (4)
drivers/hid/hid-monterey.c, (5) drivers/hid/hid-petalynx.c, and (6)
drivers/hid/hid-sunplus.c.

CVE-2014-3182: Array index error in the logi_dj_raw_event function in
drivers/hid/hid-logitech-dj.c in the Linux kernel allowed physically
proximate attackers to execute arbitrary code or cause a denial of service
(invalid kfree) via a crafted device that provides a malformed
REPORT_TYPE_NOTIF_DEVICE_UNPAIRED value.

CVE-2014-3181: Multiple stack-based buffer overflows in the
magicmouse_raw_event function in drivers/hid/hid-magicmouse.c in the Magic
Mouse HID driver in the Linux kernel allowed physically proximate
attackers to cause a denial of service (system crash) or possibly execute
arbitrary code via a crafted device that provides a large amount of (1)
EHCI or (2) XHCI data associated with an event.

CVE-2014-7826: kernel/trace/trace_syscalls.c in the Linux kernel did not
properly handle private syscall numbers during use of the ftrace
subsystem, which allowed local users to gain privileges or cause a denial
of service (invalid pointer dereference) via a crafted application.

CVE-2013-7263: The Linux kernel updated certain length values before
ensuring that associated data structures have been initialized, which
allowed local users to obtain sensitive information from kernel stack
memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call,
related to net/ipv4/ping.c, net/ipv4/raw.c, net/ipv4/udp.c,
net/ipv6/raw.c, and net/ipv6/udp.c. This update fixes the leak of the port
number when using ipv6 sockets. (bsc#853040).

CVE-2014-6410: The __udf_read_inode function in fs/udf/inode.c in the
Linux kernel did not restrict the amount of ICB indirection, which allowed
physically proximate attackers to cause a denial of service (infinite loop
or stack consumption) via a UDF filesystem with a crafted inode.

CVE-2014-5471: Stack consumption vulnerability in the
parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux
kernel allowed local users to cause a denial of service (uncontrolled
recursion, and system crash or reboot) via a crafted iso9660 image with a
CL entry referring to a directory entry that has a CL entry.

CVE-2014-5472: The parse_rock_ridge_inode_internal function in
fs/isofs/rock.c in the Linux kernel allowed local users to cause a denial
of service (unkillable mount process) via a crafted iso9660 image with a
self-referential CL entry.

CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel on 32-bit
x86 platforms, when syscall auditing is enabled and the sep CPU feature
flag is set, allowed local users to cause a denial of service (OOPS and
system crash) via an invalid syscall number, as demonstrated by number
1000.

CVE-2014-4943: The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux
kernel allowed local users to gain privileges by leveraging data-structure
differences between an l2tp socket and an inet socket.

CVE-2014-5077: The sctp_assoc_update function in net/sctp/associola.c in
the Linux kernel, when SCTP authentication is enabled, allowed remote
attackers to cause a denial of service (NULL pointer dereference and OOPS)
by starting to establish an association between two endpoints immediately
after an exchange of INIT and INIT ACK chunks to establish an earlier
association between these endpoints in the opposite direction.

CVE-2014-4171: mm/shmem.c in the Linux kernel did not properly implement
the interaction between range notification and hole punching, which
allowed local users to cause a denial of service (i_mutex hold) by using
the mmap system call to access a hole, as demonstrated by interfering with
intended shmem activity by blocking completion of (1) an MADV_REMOVE
madvise call or (2) an FALLOC_FL_PUNCH_HOLE fallocate call.

Device (HID) subsystem in the Linux kernel allowed physically proximate
