Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

    descriptionBen Hawkes discovered an integer overflow in the Linux netfilter implementation. On systems running 32 bit kernels, a local unprivileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-3135) It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before referencing it after an error condition occurred.

A vulnerability was found in the Linux kernel in function
rds_inc_info_copy of file net/rds/recv.c. The last field 'flags' of
object 'minfo' is not initialized. This can leak data previously at
the flags location to userspace. (CVE-2016-5244)

    descriptionThe SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. Notable new features : - Toleration of newer crypto hardware for z Systems - USB 2.0 Link power management for Haswell-ULT The following security bugs were fixed : - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bnc#1031579) - CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux kernel was too late in obtaining a certain lock and consequently could not ensure that disconnect function calls are safe, which allowed local users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a socket system call (bnc#1031003) - CVE-2017-7184: The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel did not validate certain size data after an XFRM_MSG_NEWAE update, which allowed local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability (bsc#1030573). - CVE-2017-5970: The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a denial of service (system crash) via (1) an application that made crafted system calls or possibly (2) IPv4 traffic with invalid IP options (bsc#1024938). - CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel allowed local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation (bsc#1033336). - CVE-2017-7294: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate addition of certain levels data, which allowed local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440) - CVE-2017-7261: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not check for a zero value of certain levels data, which allowed local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031052) - CVE-2017-7187: The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel allowed local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function (bnc#1030213) - CVE-2017-6348: The hashbin_delete function in net/irda/irqueue.c in the Linux kernel improperly managed lock dropping, which allowed local users to cause a denial of service (deadlock) via crafted operations on IrDA devices (bnc#1027178) - CVE-2017-5669: The do_shmat function in ipc/shm.c in the Linux kernel did not restrict the address calculated by a certain rounding operation, which allowed local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget and shmat system calls in a privileged context (bnc#1026914) - CVE-2015-3288: mm/memory.c in the Linux kernel mishandled anonymous pages, which allowed local users to gain privileges or cause a denial of service (page tainting) via a crafted application that triggers writing to page zero (bsc#979021). - CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by making multiple bind system calls without properly ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c (bnc#1028415) - CVE-2016-5243: The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel did not properly copy a certain string, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#983212) - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did not properly restrict association peel-off operations during certain wait states, which allowed local users to cause a denial of service (invalid unlock and double free) via a multithreaded application (bnc#1027066) - CVE-2017-6214: The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel allowed remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag (bnc#1026722) - CVE-2017-6074: The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel mishandled DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allowed local users to obtain root privileges or cause a denial of service (double free) via an application that made an IPV6_RECVPKTINFO setsockopt system call (bnc#1026024) - CVE-2017-5986: Race condition in the sctp_wait_for_sndbuf function in net/sctp/socket.c in the Linux kernel allowed local users to cause a denial of service (assertion failure and panic) via a multithreaded application that peels off an association in a certain buffer-full state (bsc#1025235) - CVE-2015-8970: crypto/algif_skcipher.c in the Linux kernel did not verify that a setkey operation has been performed on an AF_ALG socket an accept system call is processed, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted application that does not supply a key, related to the lrw_crypt function in crypto/lrw.c (bsc#1008374).

"The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
security and bugfixes. Notable new features :

  - Toleration of newer crypto hardware for z Systems

  - USB 2.0 Link power management for Haswell-ULT The
    following security bugs were fixed :

  - CVE-2017-7308: The packet_set_ring function in
    net/packet/af_packet.c in the Linux kernel did not
    properly validate certain block-size data, which allowed
    local users to cause a denial of service (overflow) or
    possibly have unspecified other impact via crafted
    system calls (bnc#1031579)

  - CVE-2017-2671: The ping_unhash function in
    net/ipv4/ping.c in the Linux kernel was too late in
    obtaining a certain lock and consequently could not
    ensure that disconnect function calls are safe, which
    allowed local users to cause a denial of service (panic)
    by leveraging access to the protocol value of
    IPPROTO_ICMP in a socket system call (bnc#1031003)

  - CVE-2017-7184: The xfrm_replay_verify_len function in
    net/xfrm/xfrm_user.c in the Linux kernel did not
    validate certain size data after an XFRM_MSG_NEWAE
    update, which allowed local users to obtain root
    privileges or cause a denial of service (heap-based
    out-of-bounds access) by leveraging the CAP_NET_ADMIN
    capability (bsc#1030573).

  - CVE-2017-5970: The ipv4_pktinfo_prepare function in
    net/ipv4/ip_sockglue.c in the Linux kernel allowed
    attackers to cause a denial of service (system crash)
    via (1) an application that made crafted system calls or
    possibly (2) IPv4 traffic with invalid IP options
    (bsc#1024938).

  - CVE-2017-7616: Incorrect error handling in the
    set_mempolicy and mbind compat syscalls in
    mm/mempolicy.c in the Linux kernel allowed local users
    to obtain sensitive information from uninitialized stack
    data by triggering failure of a certain bitmap operation
    (bsc#1033336).

  - CVE-2017-7294: The vmw_surface_define_ioctl function in
    drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux
    kernel did not validate addition of certain levels data,
    which allowed local users to trigger an integer overflow
    and out-of-bounds write, and cause a denial of service
    (system hang or crash) or possibly gain privileges, via
    a crafted ioctl call for a /dev/dri/renderD* device
    (bnc#1031440)

  - CVE-2017-7261: The vmw_surface_define_ioctl function in
    drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux
    kernel did not check for a zero value of certain levels
    data, which allowed local users to cause a denial of
    service (ZERO_SIZE_PTR dereference, and GPF and possibly
    panic) via a crafted ioctl call for a /dev/dri/renderD*
    device (bnc#1031052)

  - CVE-2017-7187: The sg_ioctl function in
    drivers/scsi/sg.c in the Linux kernel allowed local
    users to cause a denial of service (stack-based buffer
    overflow) or possibly have unspecified other impact via
    a large command size in an SG_NEXT_CMD_LEN ioctl call,
    leading to out-of-bounds write access in the sg_write
    function (bnc#1030213)

  - CVE-2017-6348: The hashbin_delete function in
    net/irda/irqueue.c in the Linux kernel improperly
    managed lock dropping, which allowed local users to
    cause a denial of service (deadlock) via crafted
    operations on IrDA devices (bnc#1027178)

  - CVE-2017-5669: The do_shmat function in ipc/shm.c in the
    Linux kernel did not restrict the address calculated by
    a certain rounding operation, which allowed local users
    to map page zero, and consequently bypass a protection
    mechanism that exists for the mmap system call, by
    making crafted shmget and shmat system calls in a
    privileged context (bnc#1026914)

  - CVE-2015-3288: mm/memory.c in the Linux kernel
    mishandled anonymous pages, which allowed local users to
    gain privileges or cause a denial of service (page
    tainting) via a crafted application that triggers
    writing to page zero (bsc#979021).

  - CVE-2016-10200: Race condition in the L2TPv3 IP
    Encapsulation feature in the Linux kernel allowed local
    users to gain privileges or cause a denial of service
    (use-after-free) by making multiple bind system calls
    without properly ascertaining whether a socket has the
    SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and
    net/l2tp/l2tp_ip6.c (bnc#1028415)

  - CVE-2016-5243: The tipc_nl_compat_link_dump function in
    net/tipc/netlink_compat.c in the Linux kernel did not
    properly copy a certain string, which allowed local
    users to obtain sensitive information from kernel stack
    memory by reading a Netlink message (bnc#983212)

  - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did
    not properly restrict association peel-off operations
    during certain wait states, which allowed local users to
    cause a denial of service (invalid unlock and double
    free) via a multithreaded application (bnc#1027066)

  - CVE-2017-6214: The tcp_splice_read function in
    net/ipv4/tcp.c in the Linux kernel allowed remote
    attackers to cause a denial of service (infinite loop
    and soft lockup) via vectors involving a TCP packet with
    the URG flag (bnc#1026722)

  - CVE-2017-6074: The dccp_rcv_state_process function in
    net/dccp/input.c in the Linux kernel mishandled
    DCCP_PKT_REQUEST packet data structures in the LISTEN
    state, which allowed local users to obtain root
    privileges or cause a denial of service (double free)
    via an application that made an IPV6_RECVPKTINFO
    setsockopt system call (bnc#1026024)

  - CVE-2017-5986: Race condition in the
    sctp_wait_for_sndbuf function in net/sctp/socket.c in
    the Linux kernel allowed local users to cause a denial
    of service (assertion failure and panic) via a
    multithreaded application that peels off an association
    in a certain buffer-full state (bsc#1025235)

  - CVE-2015-8970: crypto/algif_skcipher.c in the Linux
    kernel did not verify that a setkey operation has been
    performed on an AF_ALG socket an accept system call is
    processed, which allowed local users to cause a denial
    of service (NULL pointer dereference and system crash)
    via a crafted application that does not supply a key,
    related to the lrw_crypt function in crypto/lrw.c
    (bsc#1008374).

    in checking whether an overwrite of an skb data
    structure may occur, which allowed local users to cause
    a denial of service (system crash) via crafted system
    calls (bnc#1041431).

  - CVE-2017-10661: Race condition in fs/timerfd.c in the
    Linux kernel allowed local users to gain privileges or
    cause a denial of service (list corruption or
    use-after-free) via simultaneous file-descriptor
    operations that leverage improper might_cancel queueing
    (bnc#1053152).

  - CVE-2017-11176: The mq_notify function in the Linux
    kernel did not set the sock pointer to NULL upon entry
    into the retry logic. During a user-space close of a
    Netlink socket, it allowed attackers to cause a denial
    of service (use-after-free) or possibly have unspecified
    other impact (bnc#1048275).

  - CVE-2017-11473: Buffer overflow in the
    mp_override_legacy_irq() function in
    arch/x86/kernel/acpi/boot.c in the Linux kernel allowed
    local users to gain privileges via a crafted ACPI table
    (bnc#1049603).

  - CVE-2017-12762: In /drivers/isdn/i4l/isdn_net.c: A
    user-controlled buffer is copied into a local buffer of
    constant size using strcpy without a length check which
    can cause a buffer overflow. (bnc#1053148).

  - CVE-2017-14051: An integer overflow in the
    qla2x00_sysfs_write_optrom_ctl function in
    drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel
    allowed local users to cause a denial of service (memory
    corruption and system crash) by leveraging root access
    (bnc#1056588).

  - CVE-2017-1000112: Fixed a race condition in net-packet
    code that could have been exploited by unprivileged
    users to gain root access. (bsc#1052311).

  - CVE-2017-1000363: Linux drivers/char/lp.c Out-of-Bounds
    Write. Due to a missing bounds check, and the fact that
    parport_ptr integer is static, a 'secure boot' kernel
    command line adversary could have overflowed the
    parport_nr array in the following code (bnc#1039456).

  - CVE-2017-1000365: The Linux Kernel imposes a size
    restriction on the arguments and environmental strings
    passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the
    size), but did not take the argument and environment
    pointers into account, which allowed attackers to bypass
    this limitation (bnc#1039354).

  - CVE-2017-1000380: sound/core/timer.c in the Linux kernel
    was vulnerable to a data race in the ALSA /dev/snd/timer
    driver resulting in local users being able to read
    information belonging to other users, i.e.,
    uninitialized memory contents may be disclosed when a
    read and an ioctl happen at the same time (bnc#1044125).

The update package also includes non-security fixes. See advisory for

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

  - CVE-2015-7515, CVE-2016-2184, CVE-2016-2185,
    CVE-2016-2186, CVE-2016-2187, CVE-2016-3136,
    CVE-2016-3137, CVE-2016-3138, CVE-2016-3140
    Ralf Spenneberg of OpenSource Security reported that
    various USB drivers do not sufficiently validate USB
    descriptors. This allowed a physically present user with
    a specially designed USB device to cause a denial of
    service (crash).

  - CVE-2016-0821
    Solar Designer noted that the list 'poisoning' feature,
    intended to mitigate the effects of bugs in list
    manipulation in the kernel, used poison values within
    the range of virtual addresses that can be allocated by
    user processes.

  - CVE-2016-1237
    David Sinquin discovered that nfsd does not check
    permissions when setting ACLs, allowing users to grant
    themselves permissions to a file by setting the ACL.

  - CVE-2016-1583
    Jann Horn of Google Project Zero reported that the
    eCryptfs filesystem could be used together with the proc
    filesystem to cause a kernel stack overflow. If the
    ecryptfs-utils package is installed, local users could
    exploit this, via the mount.ecryptfs_private program,
    for denial of service (crash) or possibly for privilege
    escalation.

  - CVE-2016-2117
    Justin Yackoski of Cryptonite discovered that the
    Atheros L2 ethernet driver incorrectly enables
    scatter/gather I/O. A remote attacker could take
    advantage of this flaw to obtain potentially sensitive
    information from kernel memory.

  - CVE-2016-2143
    Marcin Koscielnicki discovered that the fork
    implementation in the Linux kernel on s390 platforms
    mishandles the case of four page-table levels, which
    allows local users to cause a denial of service (system
    crash).

  - CVE-2016-3070
    Jan Stancek of Red Hat discovered a local denial of
    service vulnerability in AIO handling.

  - CVE-2016-3134
    The Google Project Zero team found that the netfilter
    subsystem does not sufficiently validate filter table
    entries. A user with the CAP_NET_ADMIN capability could
    use this for denial of service (crash) or possibly for
    privilege escalation. Debian disables unprivileged user
    namespaces by default, if locally enabled with the
    kernel.unprivileged_userns_clone sysctl, this allows
    privilege escalation.

  - CVE-2016-3156
    Solar Designer discovered that the IPv4 implementation
    in the Linux kernel did not perform the destruction of
    inet device objects properly. An attacker in a guest OS
    could use this to cause a denial of service (networking
    outage) in the host OS.

  - CVE-2016-3157 / XSA-171
    Andy Lutomirski discovered that the x86_64 (amd64) task
    switching implementation did not correctly update the
    I/O permission level when running as a Xen paravirtual
    (PV) guest. In some configurations this would allow
    local users to cause a denial of service (crash) or to
    escalate their privileges within the guest.

  - CVE-2016-3672
    Hector Marco and Ismael Ripoll noted that it was
    possible to disable Address Space Layout Randomisation
    (ASLR) for x86_32 (i386) programs by removing the stack
    resource limit. This made it easier for local users to
    exploit security flaws in programs that have the setuid
    or setgid flag set.

  - CVE-2016-3951
    It was discovered that the cdc_ncm driver would free
    memory prematurely if certain errors occurred during its
    initialisation. This allowed a physically present user
    with a specially designed USB device to cause a denial
    of service (crash) or possibly to escalate their
    privileges.

  - CVE-2016-3955
    Ignat Korchagin reported that the usbip subsystem did
    not check the length of data received for a USB buffer.
    This allowed denial of service (crash) or privilege
    escalation on a system configured as a usbip client, by
    the usbip server or by an attacker able to impersonate
    it over the network. A system configured as a usbip
    server might be similarly vulnerable to physically
    present users.

  - CVE-2016-3961 / XSA-174
    Vitaly Kuznetsov of Red Hat discovered that Linux
    allowed the use of hugetlbfs on x86 (i386 and amd64)
    systems even when running as a Xen paravirtualised (PV)
    guest, although Xen does not support huge pages. This
    allowed users with access to /dev/hugepages to cause a
    denial of service (crash) in the guest.

  - CVE-2016-4470
    David Howells of Red Hat discovered that a local user
    can trigger a flaw in the Linux kernel's handling of key
    lookups in the keychain subsystem, leading to a denial
    of service (crash) or possibly to privilege escalation.

  - CVE-2016-4482, CVE-2016-4485, CVE-2016-4486,
    CVE-2016-4569, CVE-2016-4578, CVE-2016-4580,
    CVE-2016-5243, CVE-2016-5244

    Kangjie Lu reported that the USB devio, llc, rtnetlink,
    ALSA timer, x25, tipc, and rds facilities leaked
    information from the kernel stack.

  - CVE-2016-4565
    Jann Horn of Google Project Zero reported that various
    components in the InfiniBand stack implemented unusual
    semantics for the write() operation. On a system with
    InfiniBand drivers loaded, local users could use this
    for denial of service or privilege escalation.

  - CVE-2016-4581
    Tycho Andersen discovered that in some situations the
    Linux kernel did not handle propagated mounts correctly.
    A local user can take advantage of this flaw to cause a
    denial of service (system crash).

  - CVE-2016-4805
    Baozeng Ding discovered a use-after-free in the generic
    PPP layer in the Linux kernel. A local user can take
    advantage of this flaw to cause a denial of service
    (system crash), or potentially escalate their
    privileges.

  - CVE-2016-4913
    Al Viro found that the ISO9660 filesystem implementation
    did not correctly count the length of certain invalid
    name entries. Reading a directory containing such name
    entries would leak information from kernel memory. Users
    permitted to mount disks or disk images could use this
    to obtain sensitive information.

  - CVE-2016-4997 / CVE-2016-4998
    Jesse Hertz and Tim Newsham discovered that missing
    input sanitising in Netfilter socket handling may result
    in denial of service. Debian disables unprivileged user
    namespaces by default, if locally enabled with the
    kernel.unprivileged_userns_clone sysctl, this also
    allows privilege escalation."

  • NASL familySuSE Local Security Checks
    NASL idSUSE_SU-2017-1247-1.NASL
    descriptionThe SUSE Linux Enterprise 12 GA LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-1350: The VFS subsystem in the Linux kernel provided an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939). - CVE-2016-2117: The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly enabled scatter/gather I/O, which allowed remote attackers to obtain sensitive information from kernel memory by reading packet data (bnc#968697). - CVE-2016-3070: The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel improperly interacted with mm/migrate.c, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move (bnc#979215). - CVE-2016-5243: The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel did not properly copy a certain string, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#983212). - CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077). - CVE-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel mismanages the #BP and #OF exceptions, which allowed guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest (bnc#1015703). - CVE-2016-10044: The aio_mount function in fs/aio.c in the Linux kernel did not properly restrict execute access, which made it easier for local users to bypass intended SELinux W^X policy restrictions, and consequently gain privileges, via an io_setup system call (bnc#1023992). - CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by making multiple bind system calls without properly ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c (bnc#1028415). - CVE-2016-10208: The ext4_fill_super function in fs/ext4/super.c in the Linux kernel did not properly validate meta block groups, which allowed physically proximate attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image (bnc#1023377). - CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux kernel is too late in obtaining a certain lock and consequently cannot ensure that disconnect function calls are safe, which allowed local users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a socket system call (bnc#1031003). - CVE-2017-5669: The do_shmat function in ipc/shm.c in the Linux kernel did not restrict the address calculated by a certain rounding operation, which allowed local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget and shmat system calls in a privileged context (bnc#1026914). - CVE-2017-5897: The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allowed remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access (bnc#1023762). - CVE-2017-5970: The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a denial of service (system crash) via (1) an application that made crafted system calls or possibly (2) IPv4 traffic with invalid IP options (bnc#1024938). - CVE-2017-5986: Race condition in the sctp_wait_for_sndbuf function in net/sctp/socket.c in the Linux kernel allowed local users to cause a denial of service (assertion failure and panic) via a multithreaded application that peels off an association in a certain buffer-full state (bnc#1025235). - CVE-2017-6074: The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel mishandled DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allowed local users to obtain root privileges or cause a denial of service (double free) via an application that made an IPV6_RECVPKTINFO setsockopt system call (bnc#1026024). - CVE-2017-6214: The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel allowed remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag (bnc#1026722). - CVE-2017-6345: The LLC subsystem in the Linux kernel did not ensure that a certain destructor exists in required circumstances, which allowed local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls (bnc#1027190). - CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux kernel allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a multithreaded application that made PACKET_FANOUT setsockopt system calls (bnc#1027189). - CVE-2017-6348: The hashbin_delete function in net/irda/irqueue.c in the Linux kernel improperly managed lock dropping, which allowed local users to cause a denial of service (deadlock) via crafted operations on IrDA devices (bnc#1027178). - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did not properly restrict association peel-off operations during certain wait states, which allowed local users to cause a denial of service (invalid unlock and double free) via a multithreaded application. NOTE: this vulnerability exists because of an incorrect fix for CVE-2017-5986 (bnc#1027066). - CVE-2017-7187: The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel allowed local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function (bnc#1030213). - CVE-2017-7261: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not check for a zero value of certain levels data, which allowed local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031052). - CVE-2017-7294: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate addition of certain levels data, which allowed local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440). - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bnc#1031579). - CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel allowed local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation (bnc#1033336). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionBen Hawkes discovered an integer overflow in the Linux netfilter implementation. On systems running 32 bit kernels, a local unprivileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-3135) It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before referencing it after an error condition occurred. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-4470) Sasha Levin discovered that a use-after-free existed in the percpu allocator in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-4794) Kangjie Lu discovered an information leak in the netlink implementation of the Linux kernel. A local attacker could use this to obtain sensitive information from kernel memory. (CVE-2016-5243). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
