The validate_event function in arch/arm/kernel/perf_event.c in the Linux kernel before 3.10.8 on the ARM platform allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) by adding a hardware event to an event group led by a software event.

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.patc     h

  - 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-2014-0691).

  - 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     attributes.

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

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

Multiple vulnerabilities has been found and corrected in the Linux kernel :

Multiple array index errors in drivers/hid/hid-core.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11 allow physically proximate attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted device that provides an invalid Report ID (CVE-2013-2888).

drivers/hid/hid-zpff.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_ZEROPLUS is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device (CVE-2013-2889).

drivers/hid/hid-pl.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_PANTHERLORD is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device (CVE-2013-2892).

The Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_LOGITECH_FF, CONFIG_LOGIG940_FF, or CONFIG_LOGIWHEELS_FF is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device, related to (1) drivers/hid/hid-lgff.c, (2) drivers/hid/hid-lg3ff.c, and (3) drivers/hid/hid-lg4ff.c (CVE-2013-2893).

drivers/hid/hid-logitech-dj.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_LOGITECH_DJ is enabled, allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) or obtain sensitive information from kernel memory via a crafted device (CVE-2013-2895).

drivers/hid/hid-ntrig.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_NTRIG is enabled, allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) via a crafted device (CVE-2013-2896).

Multiple array index errors in drivers/hid/hid-multitouch.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_MULTITOUCH is enabled, allow physically proximate attackers to cause a denial of service (heap memory corruption, or NULL pointer dereference and OOPS) via a crafted device (CVE-2013-2897).

drivers/hid/hid-picolcd_core.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_PICOLCD is enabled, allows physically proximate attackers to cause a denial of service (NULL pointer dereference and OOPS) via a crafted device (CVE-2013-2899).

The udp_v6_push_pending_frames function in net/ipv6/udp.c in the IPv6 implementation in the Linux kernel through 3.10.3 makes an incorrect function call for pending data, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call (CVE-2013-4162).

The ip6_append_data_mtu function in net/ipv6/ip6_output.c in the IPv6 implementation in the Linux kernel through 3.10.3 does not properly maintain information about whether the IPV6_MTU setsockopt option had been specified, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call (CVE-2013-4163).

The validate_event function in arch/arm/kernel/perf_event.c in the Linux kernel before 3.10.8 on the ARM platform allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) by adding a hardware event to an event group led by a software event (CVE-2013-4254

The updated packages provides a solution for these security issues.

The 3.10.9 stable update contains a number of important fixes across the tree.
