This script is Copyright (C) 2014-2015 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

Description :

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.

CVE-2013-2888, CVE-2013-2889, CVE-2013-2890, CVE-2013-2891,
CVE-2013-2892, CVE-2013-2893, CVE-2013-2894, CVE-2013-2895,
CVE-2013-2896, CVE-2013-2897, CVE-2013-2898, CVE-2013-2899: Multiple
issues in the Human Interface Device (HID) subsystem in the Linux
kernel allowed physically proximate attackers to cause a denial of
service or system crash via (heap-based out-of-bounds write) via a
crafted device. (Not separately listed.)
