openSUSE Security Update : kernel (openSUSE-SU-2014:0677-1)

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

Synopsis :

The remote openSUSE host is missing a security update.

Description :

The Linux Kernel was updated to fix various security issues and bugs.

Main security issues fixed :

A security issue in the tty layer that was fixed that could be used by
local attackers for code execution (CVE-2014-0196).

Two security issues in the floppy driver were fixed that could be used
by local attackers on machines with the floppy to crash the kernel or
potentially execute code in the kernel (CVE-2014-1737 CVE-2014-1738).

Other security issues and bugs that were fixed :

- netfilter: nf_nat: fix access to uninitialized buffer in
IRC NAT helper (bnc#860835 CVE-2014-1690).

- net: sctp: fix sctp_sf_do_5_1D_ce to verify if we/peer
is AUTH (bnc#866102, CVE-2014-0101).

- n_tty: Fix a n_tty_write crash and code execution when
echoing in raw mode (bnc#871252 bnc#875690

- netfilter: nf_ct_sip: support Cisco 7941/7945 IP phones

- Update config files: re-enable twofish crypto support
Software twofish crypto support was disabled in several
architectures since openSUSE 10.3. For i386 and x86_64
it was on purpose, because hardware-accelerated
alternatives exist. However for all other architectures
it was by accident. Re-enable software twofish crypto
support in arm, ia64 and ppc configuration files, to
guarantee that at least one implementation is always
available (bnc#871325).

- Update config files: disable CONFIG_TOUCHSCREEN_W90X900
The w90p910_ts driver only makes sense on the W90x900
architecture, which we do not support.

- ath9k: protect tid->sched check

- Fix dst_neigh_lookup/dst_neigh_lookup_skb return value
handling bug (bnc#869898).

- SELinux: Fix kernel BUG on empty security contexts

- hamradio/yam: fix info leak in ioctl (bnc#858872,

- wanxl: fix info leak in ioctl (bnc#858870,

- farsync: fix info leak in ioctl (bnc#858869,

- ARM: 7809/1: perf: fix event validation for software
group leaders (CVE-2013-4254, bnc#837111).

- netfilter: nf_conntrack_dccp: fix skb_header_pointer API
usages (bnc#868653, CVE-2014-2523).

- ath9k_htc: properly set MAC address and BSSID mask
(bnc#851426, CVE-2013-4579).

- drm/ttm: don't oops if no invalidate_caches()

- Apply missing

- xfs: growfs: use uncached buffers for new headers

- xfs: use btree block initialisation functions in growfs

- Revert 'Delete
-the-filesystem-end.' (bnc#858233) Put back again the
-the-filesystem-end back as there is a better fix than
reverting the affecting patch.

- Delete
-the-filesystem-end. It turned out that this patch
causes regressions (bnc#858233) The upstream 3.7.x also
reverted it in the end (commit c3793e0d94af2).

- tcp: syncookies: reduce cookie lifetime to 128 seconds

- tcp: syncookies: reduce mss table to four values

- x86, cpu, amd: Add workaround for family 16h, erratum
793 (bnc#852967 CVE-2013-6885).

- cifs: ensure that uncached writes handle unmapped areas
correctly (bnc#864025 CVE-2014-0691).

- x86, fpu, amd: Clear exceptions in AMD FXSAVE workaround
(bnc#858638 CVE-2014-1438).

- xencons: generalize use of add_preferred_console()
(bnc#733022, bnc#852652).

- balloon: don't crash in HVM-with-PoD guests.

- hwmon: (coretemp) Fix truncated name of alarm

- NFS: Avoid PUTROOTFH when managing leases (bnc#811746).

- cifs: delay super block destruction until all
cifsFileInfo objects are gone (bnc#862145).
