  • SLE 11 SERVER Unsupported Extras

  • An update that fixes 22 vulnerabilities is now available. It includes one version update.

    Description:


    The SUSE Linux Enterprise Server 11 SP1 LTSS received a roll up update to
    fix several security and non-security issues.

    The following security issues have been fixed:

    * CVE-2013-1860: Heap-based buffer overflow in the wdm_in_callback
    function in drivers/usb/class/cdc-wdm.c in the Linux kernel before
    3.8.4 allows physically proximate attackers to cause a denial of
    service (system crash) or possibly execute arbitrary code via a
    crafted cdc-wdm USB device. (bnc#806431)
    * CVE-2013-4162: 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. (bnc#831058)
    * CVE-2014-0203: The __do_follow_link function in fs/namei.c in the
    Linux kernel before 2.6.33 does not properly handle the last
    pathname component during use of certain filesystems, which allows
    local users to cause a denial of service (incorrect free operations
    and system crash) via an open system call. (bnc#883526)
    * 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-2014-4943: The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the
    Linux kernel through 3.15.6 allows local users to gain privileges by
    leveraging data-structure differences between an l2tp socket and an
    inet socket. (bnc#887082)
    * 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-2013-7266: The mISDN_sock_recvmsg function in
    drivers/isdn/mISDN/socket.c in the Linux kernel before 3.12.4 does
    not ensure that a certain length value is consistent with the size
    of an associated data structure, which allows local users to obtain
    sensitive information from kernel memory via a (1) recvfrom, (2)
    recvmmsg, or (3) recvmsg system call. (bnc#854722)
    * CVE-2013-7267: The atalk_recvmsg function in net/appletalk/ddp.c in
    the Linux kernel before 3.12.4 updates a certain length value
    without ensuring that an associated data structure has been
    initialized, which allows local users to obtain sensitive
    information from kernel memory via a (1) recvfrom, (2) recvmmsg, or
    (3) recvmsg system call. (bnc#854722)
    * CVE-2013-7268: The ipx_recvmsg function in net/ipx/af_ipx.c in the
    Linux kernel before 3.12.4 updates a certain length value without
    ensuring that an associated data structure has been initialized,
    which allows local users to obtain sensitive information from kernel
    memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call.
    (bnc#854722)
    * CVE-2013-7269: The nr_recvmsg function in net/netrom/af_netrom.c in
    the Linux kernel before 3.12.4 updates a certain length value
    without ensuring that an associated data structure has been
    initialized, which allows local users to obtain sensitive
    information from kernel memory via a (1) recvfrom, (2) recvmmsg, or
    (3) recvmsg system call. (bnc#854722)
    * CVE-2013-7270: The packet_recvmsg function in net/packet/af_packet.c
    in the Linux kernel before 3.12.4 updates a certain length value
    before ensuring that an associated data structure has been
    initialized, which allows local users to obtain sensitive
    information from kernel memory via a (1) recvfrom, (2) recvmmsg, or
    (3) recvmsg system call. (bnc#854722)
    * CVE-2013-7271: The x25_recvmsg function in net/x25/af_x25.c in the
    Linux kernel before 3.12.4 updates a certain length value without
    ensuring that an associated data structure has been initialized,
    which allows local users to obtain sensitive information from kernel
    memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call.
    (bnc#854722)
