______________________________________________________________________________

   An update that solves 18 vulnerabilities and has 8 fixes is
   now available. It includes one version update.

Description:


   The SUSE Linux Enterprise Server 11 SP2 LTSS received a roll up update to
   fix several security and non-security issues.

   The following security issues have been fixed:

       * CVE-2014-0055: The get_rx_bufs function in drivers/vhost/net.c in
         the vhost-net subsystem in the Linux kernel package before
         2.6.32-431.11.2 on Red Hat Enterprise Linux (RHEL) 6 does not
         properly handle vhost_get_vq_desc errors, which allows guest OS
         users to cause a denial of service (host OS crash) via unspecified
         vectors. (bnc#870173)
       * CVE-2014-0077: drivers/vhost/net.c in the Linux kernel before
         3.13.10, when mergeable buffers are disabled, does not properly
         validate packet lengths, which allows guest OS users to cause a
         denial of service (memory corruption and host OS crash) or possibly
         gain privileges on the host OS via crafted packets, related to the
         handle_rx and get_rx_bufs functions. (bnc#870576)
       * CVE-2014-1739: The media_device_enum_entities function in
         drivers/media/media-device.c in the Linux kernel before 3.14.6 does
         not initialize a certain data structure, which allows local users to
         obtain sensitive information from kernel memory by leveraging
   /dev/media0 read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call.
   (bnc#882804)
       * CVE-2014-2706: Race condition in the mac80211 subsystem in the Linux
         kernel before 3.13.7 allows remote attackers to cause a denial of
         service (system crash) via network traffic that improperly interacts
         with the WLAN_STA_PS_STA state (aka power-save mode), related to
         sta_info.c and tx.c. (bnc#871797)
       * CVE-2014-2851: Integer overflow in the ping_init_sock function in
         net/ipv4/ping.c in the Linux kernel through 3.14.1 allows local
         users to cause a denial of service (use-after-free and system crash)
         or possibly gain privileges via a crafted application that leverages
         an improperly managed reference counter. (bnc#873374)
       * CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2)
         BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter
         function in net/core/filter.c in the Linux kernel through 3.14.3 do
         not check whether a certain length value is sufficiently large,
         which allows local users to cause a denial of service (integer
         underflow and system crash) via crafted BPF instructions. NOTE: the
         affected code was moved to the __skb_get_nlattr and
         __skb_get_nlattr_nest functions before the vulnerability was
         announced. (bnc#877257)
       * CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension implementation in
         the sk_run_filter function in net/core/filter.c in the Linux kernel
         through 3.14.3 uses the reverse order in a certain subtraction,
         which allows local users to cause a denial of service (over-read and
         system crash) via crafted BPF instructions. NOTE: the affected code
         was moved to the __skb_get_nlattr_nest function before the
         vulnerability was announced. (bnc#877257)
       * CVE-2014-3917: kernel/auditsc.c in the Linux kernel through 3.14.5,
         when CONFIG_AUDITSYSCALL is enabled with certain syscall rules,
         allows local users to obtain potentially sensitive single-bit values
         from kernel memory or cause a denial of service (OOPS) via a large
         value of a syscall number. (bnc#880484)
       * CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel
         through 3.15.1 on 32-bit x86 platforms, when syscall auditing is
         enabled and the sep CPU feature flag is set, allows local users to
         cause a denial
         of service (OOPS and system crash) via an invalid syscall number, as
   demonstrated by number 1000. (bnc#883724)
       * CVE-2014-4652: Race condition in the tlv handler functionality in
         the snd_ctl_elem_user_tlv function in sound/core/control.c in the
         ALSA control implementation in the Linux kernel before 3.15.2 allows
         local users to obtain sensitive information from kernel memory by
         leveraging /dev/snd/controlCX access. (bnc#883795)
       * CVE-2014-4653: sound/core/control.c in the ALSA control
         implementation in the Linux kernel before 3.15.2 does not ensure
         possession of a read/write lock, which allows local users to cause a
         denial of service (use-after-free) and obtain sensitive information
         from kernel memory by leveraging /dev/snd/controlCX access.
         (bnc#883795)
       * CVE-2014-4654: The snd_ctl_elem_add function in sound/core/control.c
         in the ALSA control implementation in the Linux kernel before 3.15.2
         does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE
         commands, which allows local users to remove kernel controls and
         cause a denial of service (use-after-free and system crash) by
         leveraging /dev/snd/controlCX access for an ioctl call. (bnc#883795)
       * CVE-2014-4655: The snd_ctl_elem_add function in sound/core/control.c
         in the ALSA control implementation in the Linux kernel before 3.15.2
         does not properly maintain the user_ctl_count value, which allows
         local users to cause a denial of service (integer overflow and limit
         bypass) by leveraging /dev/snd/controlCX access for a large number
         of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls. (bnc#883795)
       * CVE-2014-4656: Multiple integer overflows in sound/core/control.c in
         the ALSA control implementation in the Linux kernel before 3.15.2
         allow local users to cause a denial of service by leveraging
         /dev/snd/controlCX access, related to (1) index values in the
         snd_ctl_add function and (2) numid values in the
         snd_ctl_remove_numid_conflict function. (bnc#883795)
       * CVE-2014-4667: The sctp_association_free function in
         net/sctp/associola.c in the Linux kernel before 3.15.2 does not
         properly manage a certain backlog value, which allows remote
         attackers to cause a denial of service (socket outage) via a crafted
         SCTP packet. (bnc#885422)
       * CVE-2014-4699: The Linux kernel before 3.15.4 on Intel processors
         does not properly restrict use of a non-canonical value for the
         saved RIP address in the case of a system call that does not use
         IRET, which allows local users to leverage a race condition and gain
         privileges, or cause a denial of service (double fault), via a
         crafted application that makes ptrace and fork system calls.
         (bnc#885725)
       * CVE-2014-5077: The sctp_assoc_update function in
         net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP
         authentication is enabled, allows 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.
         (bnc#889173)
       * CVE-2013-4299: Interpretation conflict in
         drivers/md/dm-snap-persistent.c in the Linux kernel through 3.11.6
         allows remote authenticated users to obtain sensitive information or
         modify data via a crafted mapping to a snapshot block device.
         (bnc#846404)

   The following bugs have been fixed:

       * pagecachelimit: reduce lru_lock contention for heavy parallel
         reclaim (bnc#878509, bnc#864464).
       * pagecachelimit: reduce lru_lock contention for heavy parallel
         reclaim kabi fixup (bnc#878509, bnc#864464).
       * ACPI / PAD: call schedule() when need_resched() is true (bnc#866911).
       * kabi: Fix breakage due to addition of user_ctl_lock (bnc#883795).
       * cpuset: Fix memory allocator deadlock (bnc#876590).
       * tcp: allow to disable cwnd moderation in TCP_CA_Loss state
         (bnc#879921).
       * tcp: adapt selected parts of RFC 5682 and PRR logic (bnc#879921).
       * vlan: more careful checksum features handling (bnc#872634).
       * bonding: fix vlan_features computing (bnc#872634).
       * NFSv4: Minor cleanups for nfs4_handle_exception and
         nfs4_async_handle_error (bnc#889324).
       * NFS: Do not lose sockets when nfsd shutdown races with connection
         timeout (bnc#871854).
       * reiserfs: call truncate_setsize under tailpack mutex (bnc#878115).
       * reiserfs: drop vmtruncate (bnc#878115).
       * megaraid_sas: mask off flags in ioctl path (bnc#886474).
       * block: fix race between request completion and timeout handling
         (bnc#881051).
       * drivers/rtc/interface.c: fix infinite loop in initializing the alarm
         (bnc#871676).
       * xfrm: check peer pointer for null before calling inet_putpeer()
         (bnc#877775).
