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 CVE-2014-0196).

  • netfilter: nf_ct_sip: support Cisco 7941/7945 IP phones (bnc#873717).

  • 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 (bnc#871148,CVE-2014-2672).

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

  • SELinux: Fix kernel BUG on empty security contexts
    (bnc#863335,CVE-2014-1874).

  • hamradio/yam: fix info leak in ioctl (bnc#858872, CVE-2014-1446).

  • wanxl: fix info leak in ioctl (bnc#858870, CVE-2014-1445).

  • farsync: fix info leak in ioctl (bnc#858869, CVE-2014-1444).

  • 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() (bnc#869414).

  • Apply missing patches.fixes/drm-nouveau-hwmon-rename-fan0-to-fan1.patch

  • xfs: growfs: use uncached buffers for new headers (bnc#858233).

  • xfs: use btree block initialisation functions in growfs (bnc#858233).

  • Revert "Delete
    patches.fixes/xfs-fix-xfs_buf_find-oops-on-blocks-beyond-the-filesystem-end
    ." (bnc#858233) Put back again the patch
    patches.fixes/xfs-fix-xfs_buf_find-oops-on-blocks-beyond-the-filesystem-end
    back as there is a better fix than reverting the affecting patch.

  • Delete
    patches.fixes/xfs-fix-xfs_buf_find-oops-on-blocks-beyond-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 (bnc#833968).

  • tcp: syncookies: reduce mss table to four values (bnc#833968).

  • 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-2014-0069).

  • 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 attributes.

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

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