Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Flooding
    An attacker consumes the resources of a target by rapidly engaging in a large number of interactions with the target. This type of attack generally exposes a weakness in rate limiting or flow control in management of interactions. Since each request consumes some of the target's resources, if a sufficiently large number of requests must be processed at the same time then the target's resources can be exhausted. The degree to which the attack is successful depends upon the volume of requests in relation to the amount of the resource the target has access to, and other mitigating circumstances such as the target's ability to shift load or acquired additional resources to deal with the depletion. The more protected the resource and the greater the quantity of it that must be consumed, the more resources the attacker may need to have at their disposal. A typical TCP/IP flooding attack is a Distributed Denial-of-Service attack where many machines simultaneously make a large number of requests to a target. Against a target with strong defenses and a large pool of resources, many tens of thousands of attacking machines may be required. When successful this attack prevents legitimate users from accessing the service and can cause the target to crash. This attack differs from resource depletion through leaks or allocations in that the latter attacks do not rely on the volume of requests made to the target but instead focus on manipulation of the target's operations. The key factor in a flooding attack is the number of requests the attacker can make in a given period of time. The greater this number, the more likely an attack is to succeed against a given target.
  • Excessive Allocation
    An attacker causes the target to allocate excessive resources to servicing the attackers' request, thereby reducing the resources available for legitimate services and degrading or denying services. Usually, this attack focuses on memory allocation, but any finite resource on the target could be the attacked, including bandwidth, processing cycles, or other resources. This attack does not attempt to force this allocation through a large number of requests (that would be Resource Depletion through Flooding) but instead uses one or a small number of requests that are carefully formatted to force the target to allocate excessive resources to service this request(s). Often this attack takes advantage of a bug in the target to cause the target to allocate resources vastly beyond what would be needed for a normal request. For example, using an Integer Attack, the attacker could cause a variable that controls allocation for a request to hold an excessively large value. Excessive allocation of resources can render a service degraded or unavailable to legitimate users and can even lead to crashing of the target.
  • Resource Leak Exposure
    An attacker utilizes a resource leak on the target to deplete the quantity of the resource available to service legitimate requests. Resource leaks most often come in the form of memory leaks where memory is allocated but never released after it has served its purpose, however, theoretically, any other resource that can be reserved can be targeted if the target fails to release the reservation when the reserved resource block is no longer needed. In this attack, the attacker determines what activity results in leaked resources and then triggers that activity on the target. Since some leaks may be small, this may require a large number of requests by the attacker. However, this attack differs from a flooding attack in that the rate of requests is generally not significant. This is because the lost resources due to the leak accumulate until the target is reset, usually by restarting it. Thus, a resource-poor attacker who would be unable to flood the target can still utilize this attack. Resource depletion through leak differs from resource depletion through allocation in that, in the former, the attacker may not be able to control the size of each leaked allocation, but instead allows the leak to accumulate until it is large enough to affect the target's performance. When depleting resources through allocation, the allocated resource may eventually be released by the target so the attack relies on making sure that the allocation size itself is prohibitive of normal operations by the target.

This update adds mitigations for various side channel attacks against modern CPUs that could disclose content of otherwise unreadable memory (bnc#1068032). - CVE-2017-5753: Local attackers on systems with modern CPUs featuring deep instruction pipelining could use attacker controllable speculative execution over code patterns in the Linux Kernel to leak content from otherwise not readable memory in the same address space, allowing retrieval of passwords, cryptographic keys and other secrets. This problem is mitigated by adding speculative fencing on affected code paths throughout the Linux kernel. This issue is addressed for the x86_64, the IBM Power and IBM zSeries architecture. - CVE-2017-5715: Local attackers on systems with modern CPUs featuring branch prediction could use mispredicted branches to speculatively execute code patterns that in turn could be made to leak other non-readable content in the same address space, an attack similar to CVE-2017-5753. This problem is mitigated by disabling predictive branches, depending on CPU architecture either by firmware updates and/or fixes in the user-kernel privilege boundaries. This is done with help of Linux Kernel fixes on the Intel/AMD x86_64 and IBM zSeries architectures. On x86_64, this requires also updates of the CPU microcode packages, delivered in separate updates.

"The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
security and bugfixes. This update adds mitigations for various side
channel attacks against modern CPUs that could disclose content of
otherwise unreadable memory (bnc#1068032).

  - CVE-2017-5753: Local attackers on systems with modern
    CPUs featuring deep instruction pipelining could use
    attacker controllable speculative execution over code
    patterns in the Linux Kernel to leak content from
    otherwise not readable memory in the same address space,
    allowing retrieval of passwords, cryptographic keys and
    other secrets. This problem is mitigated by adding
    speculative fencing on affected code paths throughout
    the Linux kernel. This issue is addressed for the
    x86_64, the IBM Power and IBM zSeries architecture.

  - CVE-2017-5715: Local attackers on systems with modern
    CPUs featuring branch prediction could use mispredicted
    branches to speculatively execute code patterns that in
    turn could be made to leak other non-readable content in
    the same address space, an attack similar to
    CVE-2017-5753. This problem is mitigated by disabling
    predictive branches, depending on CPU architecture
    either by firmware updates and/or fixes in the
    user-kernel privilege boundaries. This is done with help
    of Linux Kernel fixes on the Intel/AMD x86_64 and IBM
    zSeries architectures. On x86_64, this requires also
    updates of the CPU microcode packages, delivered in
    separate updates. For IBM Power and zSeries the required
    firmware updates are supplied over regular channels by
    IBM. As this feature can have a performance impact, it
    can be disabled using the 'nospec' kernel commandline
    option.

  - CVE-2017-5754: Local attackers on systems with modern
    CPUs featuring deep instruction pipelining could use
    code patterns in userspace to speculative executive code
    that would read otherwise read protected memory, an
    attack similar to CVE-2017-5753. This problem is
    mitigated by unmapping the Linux Kernel from the user
    address space during user code execution, following a
    approach called 'KAISER'. The terms used here are
    'KAISER' / 'Kernel Address Isolation' and 'PTI' / 'Page
    Table Isolation'. This update does this on the Intel
    x86_64 and IBM Power architecture. Updates are also
    necessary for the ARM architecture, but will be
    delivered in the next round of updates. This feature can
    be enabled / disabled by the 'pti=[on|off|auto]' or
    'nopti' commandline options. The following security bugs
    were fixed :

  - CVE-2017-17806: The HMAC implementation (crypto/hmac.c)
    in the Linux kernel did not validate that the underlying
    cryptographic hash algorithm is unkeyed, allowing a
    local attacker able to use the AF_ALG-based hash
    interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3
    hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel
    stack-based buffer overflow by executing a crafted
    sequence of system calls that encounter a missing SHA-3
    initialization (bnc#1073874).

  - CVE-2017-17805: The Salsa20 encryption algorithm in the
    Linux kernel did not correctly handle zero-length
    inputs, allowing a local attacker able to use the
    AF_ALG-based skcipher interface
    (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of
    service (uninitialized-memory free and kernel crash) or
    have unspecified other impact by executing a crafted
    sequence of system calls that use the blkcipher_walk
    API. Both the generic implementation
    (crypto/salsa20_generic.c) and x86 implementation
    (arch/x86/crypto/salsa20_glue.c) of Salsa20 were
    vulnerable (bnc#1073792).

  - CVE-2017-15868: The bnep_add_connection function in
    net/bluetooth/bnep/core.c in the Linux kernel did not
    ensure that an l2cap socket is available, which allowed
    local users to gain privileges via a crafted application
    (bnc#1071470).

  - CVE-2017-13167: An elevation of privilege vulnerability
    in the kernel sound timer. (bnc#1072876).

  - CVE-2017-16538: drivers/media/usb/dvb-usb-v2/lmedm04.c
    in the Linux kernel allowed local users to cause a
    denial of service (general protection fault and system
    crash) or possibly have unspecified other impact via a
    crafted USB device, related to a missing warm-start
    check and incorrect attach timing
    (dm04_lme2510_frontend_attach versus dm04_lme2510_tuner)
    (bnc#1066569).

  - CVE-2017-17558: The usb_destroy_configuration function
    in drivers/usb/core/config.c in the USB core subsystem
    in the Linux kernel did not consider the maximum number
    of configurations and interfaces before attempting to
    release resources, which allowed local users to cause a
    denial of service (out-of-bounds write access) or
    possibly have unspecified other impact via a crafted USB
    device (bnc#1072561).

  - CVE-2017-17450: net/netfilter/xt_osf.c in the Linux
    kernel did not require the CAP_NET_ADMIN capability for
    add_callback and remove_callback operations, which
    allowed local users to bypass intended access
    restrictions because the xt_osf_fingers data structure
    is shared across all net namespaces (bnc#1071695).

  - CVE-2017-8824: The dccp_disconnect function in
    net/dccp/proto.c in the Linux kernel allowed local users
    to gain privileges or cause a denial of service
    (use-after-free) via an AF_UNSPEC connect system call
    during the DCCP_LISTEN state (bnc#1070771).

  - CVE-2017-16939: The XFRM dump policy implementation in
    net/xfrm/xfrm_user.c in the Linux kernel allowed local
    users to gain privileges or cause a denial of service
    (use-after-free) via a crafted SO_RCVBUF setsockopt
    system call in conjunction with XFRM_MSG_GETPOLICY
    Netlink messages (bnc#1069702).

  - CVE-2017-15115: The sctp_do_peeloff function in
    net/sctp/socket.c in the Linux kernel did not check
    whether the intended netns is used in a peel-off action,
    which allowed local users to cause a denial of service
    (use-after-free and system crash) or possibly have
    unspecified other impact via crafted system calls
    (bnc#1068671).

  - CVE-2017-14106: The tcp_disconnect function in
    net/ipv4/tcp.c in the Linux kernel allowed local users
    to cause a denial of service (__tcp_select_window
    divide-by-zero error and system crash) by triggering a
    disconnect within a certain tcp_recvmsg code path
    (bnc#1056982).

  - CVE-2017-11600: net/xfrm/xfrm_policy.c in the Linux
    kernel through 4.12.3, when CONFIG_XFRM_MIGRATE is
    enabled, did not ensure that the dir value of
    xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which
    allowed local users to cause a denial of service
    (out-of-bounds access) or possibly have unspecified
    other impact via an XFRM_MSG_MIGRATE xfrm Netlink
    message (bnc#1050231).

  - CVE-2017-7472: The KEYS subsystem in the Linux kernel
    allowed local users to cause a denial of service (memory
    consumption) via a series of
    KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring
    calls (bnc#1034862).

  - CVE-2017-16534: The cdc_parse_cdc_header function in
    drivers/usb/core/message.c in the Linux kernel allowed
    local users to cause a denial of service (out-of-bounds
    read and system crash) or possibly have unspecified
    other impact via a crafted USB device (bnc#1066693).

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

A local attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-8632) It was discovered that the keyring implementation in the Linux kernel in some situations did not prevent special internal keyrings from being joined by userspace keyrings. A privileged local attacker could use this to bypass module verification.

"The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive
various security and bugfixes. This update adds mitigations for
various side channel attacks against modern CPUs that could disclose
content of otherwise unreadable memory (bnc#1068032).

  - CVE-2017-5753: Local attackers on systems with modern
    CPUs featuring deep instruction pipelining could use
    attacker controllable speculative execution over code
    patterns in the Linux Kernel to leak content from
    otherwise not readable memory in the same address space,
    allowing retrieval of passwords, cryptographic keys and
    other secrets. This problem is mitigated by adding
    speculative fencing on affected code paths throughout
    the Linux kernel.

  - CVE-2017-5715: Local attackers on systems with modern
    CPUs featuring branch prediction could use mispredicted
    branches to speculatively execute code patterns that in
    turn could be made to leak other non-readable content in
    the same address space, an attack similar to
    CVE-2017-5753. This problem is mitigated by disabling
    predictive branches, depending on CPU architecture
    either by firmware updates and/or fixes in the
    user-kernel privilege boundaries. Please contact your
    CPU / hardware vendor for potential microcode or BIOS
    updates needed for this fix. As this feature can have a
    performance impact, it can be disabled using the
    'nospec' kernel commandline option.

  - CVE-2017-5754: Local attackers on systems with modern
    CPUs featuring deep instruction pipelining could use
    code patterns in userspace to speculative executive code
    that would read otherwise read protected memory, an
    attack similar to CVE-2017-5753. This problem is
    mitigated by unmapping the Linux Kernel from the user
    address space during user code execution, following a
    approach called 'KAISER'. The terms used here are
    'KAISER' / 'Kernel Address Isolation' and 'PTI' / 'Page
    Table Isolation'. This feature is disabled on unaffected
    architectures. This feature can be enabled / disabled by
    the 'pti=[on|off|auto]' or 'nopti' commandline options.
    The following security bugs were fixed :

  - CVE-2017-1000251: The native Bluetooth stack in the
    Linux Kernel (BlueZ) was vulnerable to a stack overflow
    vulnerability in the processing of L2CAP configuration
    responses resulting in Remote code execution in kernel
    space (bnc#1057389).

  - CVE-2017-11600: net/xfrm/xfrm_policy.c in the Linux
    kernel did not ensure that the dir value of
    xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which
    allowed local users to cause a denial of service
    (out-of-bounds access) or possibly have unspecified
    other impact via an XFRM_MSG_MIGRATE xfrm Netlink
    message (bnc#1050231).

  - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2)
    allowed reinstallation of the Group Temporal Key (GTK)
    during the group key handshake, allowing an attacker
    within radio range to replay frames from access points
    to clients (bnc#1063667).

    related to sound/core/seq/seq_clientmgr.c and
    sound/core/seq/seq_ports.c (bnc#1062520).

  - CVE-2017-15274: security/keys/keyctl.c in the Linux
    kernel did not consider the case of a NULL payload in
    conjunction with a nonzero length value, which allowed
    local users to cause a denial of service (NULL pointer
    dereference and OOPS) via a crafted add_key or keyctl
    system call, a different vulnerability than
    CVE-2017-12192 (bnc#1045327).

  - CVE-2017-15868: The bnep_add_connection function in
    net/bluetooth/bnep/core.c in the Linux kernel did not

  - CVE-2017-17450: net/netfilter/xt_osf.c in the Linux
    kernel did not require the CAP_NET_ADMIN capability for
    add_callback and remove_callback operations, which
    allowed local users to bypass intended access
    restrictions because the xt_osf_fingers data structure
    is shared across all net namespaces (bnc#1071695
    1074033).

  - CVE-2017-17558: The usb_destroy_configuration function
    in drivers/usb/core/config.c in the USB core subsystem
    in the Linux kernel did not consider the maximum number
    of configurations and interfaces before attempting to
    release resources, which allowed local users to cause a

    vulnerable (bnc#1073792).

  - CVE-2017-17806: The HMAC implementation (crypto/hmac.c)
    in the Linux kernel did not validate that the underlying
    cryptographic hash algorithm is unkeyed, allowing a
    local attacker able to use the AF_ALG-based hash
    interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3
    hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel
    stack-based buffer overflow by executing a crafted
    sequence of system calls that encounter a missing SHA-3
    initialization (bnc#1073874).

  - CVE-2017-7472: The KEYS subsystem in the Linux kernel
    allowed local users to cause a denial of service (memory
    consumption) via a series of
    KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring
    calls (bnc#1034862).

  - CVE-2017-8824: The dccp_disconnect function in
    net/dccp/proto.c in the Linux kernel allowed local users
    to gain privileges or cause a denial of service
    (use-after-free) via an AF_UNSPEC connect system call
    during the DCCP_LISTEN state (bnc#1070771).

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or have other impacts. CVE-2016-2188 Ralf Spenneberg of OpenSource Security reported that the iowarrior device driver did 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-2016-9604 It was discovered that the keyring subsystem allowed a process to set a special internal keyring as its session keyring. The security impact in this version of the kernel is unknown. CVE-2016-10200 Baozeng Ding and Andrey Konovalov reported a race condition in the L2TP implementation which could corrupt its table of bound sockets. A local user could use this to cause a denial of service (crash) or possibly for privilege escalation. CVE-2017-2647 / CVE-2017-6951 idl3r reported that the keyring subsystem would allow a process to search for

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

CVE-2016-2188

Ralf Spenneberg of OpenSource Security reported that the iowarrior
device driver did 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-2016-9604

It was discovered that the keyring subsystem allowed a process to set
a special internal keyring as its session keyring. The security impact
in this version of the kernel is unknown.

CVE-2016-10200

Baozeng Ding and Andrey Konovalov reported a race condition in the
L2TP implementation which could corrupt its table of bound sockets. A
local user could use this to cause a denial of service (crash) or
possibly for privilege escalation.

CVE-2017-2647 / CVE-2017-6951

idl3r reported that the keyring subsystem would allow a process to
search for 'dead' keys, causing a NULL pointer dereference. A local
user could use this to cause a denial of service (crash).

CVE-2017-2671

Daniel Jiang discovered a race condition in the ping socket
implementation. A local user with access to ping sockets could use
this to cause a denial of service (crash) or possibly for privilege
escalation. This feature is not accessible to any users by default.

CVE-2017-5967

Xing Gao reported that the /proc/timer_list file showed information
about all processes, not considering PID namespaces. If timer
debugging was enabled by a privileged user, this leaked information to
processes contained in PID namespaces.

CVE-2017-5970

Andrey Konovalov discovered a denial of service flaw in the IPv4
networking code. This can be triggered by a local or remote attacker
if a local UDP or raw socket has the IP_RETOPTS option enabled.

CVE-2017-7184

Chaitin Security Research Lab discovered that the net xfrm subsystem
did not sufficiently validate replay state parameters, allowing a heap
buffer overflow. This can be used by a local user with the
CAP_NET_ADMIN capability for privilege escalation.

CVE-2017-7261

Vladis Dronov and Murray McAllister reported that the vmwgfx driver
did not sufficiently validate rendering surface parameters. In a
VMware guest, this can be used by a local user to cause a denial of
service (crash).

CVE-2017-7273

Benoit Camredon reported that the hid-cypress driver did not
sufficiently validate HID reports. This possibly allowed a physically
present user with a specially designed USB device to cause a denial of
service (crash).

CVE-2017-7294

Li Qiang reported that the vmwgfx driver did not sufficiently validate
rendering surface parameters. In a VMware guest, this can be used by a
local user to cause a denial of service (crash) or possibly for
privilege escalation.

CVE-2017-7308

Andrey Konovalov reported that the packet socket (AF_PACKET)
implementation did not sufficiently validate buffer parameters. This
can be used by a local user with the CAP_NET_RAW capability for
privilege escalation.

CVE-2017-7472

Eric Biggers reported that the keyring subsystem allowed a thread to
create new thread keyrings repeatedly, causing a memory leak. This can
be used by a local user to cause a denial of service (memory
exhaustion).

CVE-2017-7616

Chris Salls reported an information leak in the 32-bit big-endian
compatibility implementations of set_mempolicy() and mbind(). This
does not affect any architecture supported in Debian 7 LTS.

CVE-2017-7618

Sabrina Dubroca reported that the cryptographic hash subsystem does
not correctly handle submission of unaligned data to a device that is
already busy, resulting in infinite recursion. On some systems this
can be used by local users to cause a denial of service (crash).

For Debian 7 'Wheezy', these problems have been fixed in version
3.2.88-1. This version also includes bug fixes from upstream version
3.2.88, and fixes some older security issues in the keyring, packet
socket and cryptographic hash subsystems that do not have CVE IDs.

For Debian 8 'Jessie', most of these problems have been fixed in
version 3.16.43-1 which will be part of the next point release.

We recommend that you upgrade your linux packages.

    descriptionAccording to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - It was found that keyctl_set_reqkey_keyring() function leaked thread keyring which could allow an unprivileged local user to exhaust kernel memory. - net/sctp/socket.c in the Linux kernel through 4.10.1 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. - Race condition in the sctp_wait_for_sndbuf function in net/sctp/socket.c in the Linux kernel before 4.9.11 could allow local users to cause a denial of service (assertion failure and panic) via a multithreaded application that peeled off an association in a certain buffer-full state. - Andrey Konovalov discovered that signed integer overflows existed in the setsockopt() system call when handling the SO_SNDBUFFORCE and SO_RCVBUFFORCE options. A local attacker with the CAP_NET_ADMIN capability could use this to cause a denial of service (system crash or memory corruption). - A vulnerability was discovered in the handling of pid namespaces in the kernel. A privileged user inside a container could trigger a kernel crash (NULL pointer dereference in proc_flush_task()) using a sequence of system calls including wait4(). Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.Security Fix(es):The yam_ioctl function in drivers et/hamradio/yam.c in the Linux kernel before 3.12.8 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCYAMGCFG ioctl call.(CVE-2014-1446)The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows 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.(CVE-2015-1350)A certain backport in the TCP Fast Open implementation for the Linux kernel before 3.18 does not properly maintain a count value, which allow local users to cause a denial of service (system crash) via the Fast Open feature, as demonstrated by visiting the chrome://flags/#enable-tcp-fast-open URL when using certain 3.10.x through 3.16.x kernel builds, including longterm-maintenance releases and ckt (aka Canonical Kernel Team) builds.(CVE-2015-3332)The hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device.(CVE-2015-8816)In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the userspace API. However, the code allows larger values such as 23.(CVE-2015-9289)The create_fixed_stream_quirk function in sound/usb/quirks.c in the snd-usb-audio driver in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference or double free, and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2184)The ati_remote2_probe function in drivers/input/misc/ati_remote2.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2185)The powermate_probe function in drivers/input/misc/powermate.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2186)The gtco_probe function in drivers/input/tablet/gtco.c in the Linux kernel through 4.5.2 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2187)Double free vulnerability in the snd_usbmidi_create function in sound/usb/midi.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (panic) or possibly have unspecified other impact via vectors involving an invalid USB descriptor.(CVE-2016-2384)The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint.(CVE-2016-2782)The acm_probe function in drivers/usb/class/cdc-acm.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both a control and a data endpoint descriptor.(CVE-2016-3138)The wacom_probe function in drivers/input/tablet/wacom_sys.c in the Linux kernel before 3.17 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-3139)The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-3140)The ims_pcu_parse_cdc_data function in drivers/input/misc/ims-pcu.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (system crash) via a USB device without both a master and a slave interface.(CVE-2016-3689)The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface.(CVE-2016-4569)sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.(CVE-2016-4578)The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.(CVE-2016-4580)The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code.(CVE-2016-7425)The Linux Kernel running on AMD64 systems will sometimes map the contents of PIE executable, the heap or ld.so to where the stack is mapped allowing attackers to more easily manipulate the stack. Linux Kernel version 4.11.5 is affected.(CVE-2017-1000379)In android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, a buffer overread is observed in nl80211_set_station when user space application sends attribute NL80211_ATTR_LOCAL_MESH_POWER_MODE with data of size less than 4 bytes(CVE-2017-11089)An elevation of privilege vulnerability in the kernel sound timer. Product: Android. Versions: Android kernel. Android ID A-37240993.(CVE-2017-13167)In ashmem_ioctl of ashmem.c, there is an out-of-bounds write due to insufficient locking when accessing asma. This could lead to a local elevation of privilege enabling code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-66954097.(CVE-2017-13216)A information disclosure vulnerability in the Upstream kernel encrypted-keys. Product: Android. Versions: Android kernel. Android ID: A-70526974.(CVE-2017-13305)An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel through 4.12.10 allows local users to cause a denial of service (memory corruption and system crash) by leveraging root access.(CVE-2017-14051)The Serial Attached SCSI (SAS) implementation in the Linux kernel through 4.15.9 mishandles a mutex within libsas, which allows local users to cause a denial of service (deadlock) by triggering certain error-handling code.(CVE-2017-18232)An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187.(CVE-2017-18509)An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an out of bounds write in the function i2c_smbus_xfer_emulated.(CVE-2017-18551)An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c.(CVE-2017-18595)The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows 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.(CVE-2017-7261)The KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls.(CVE-2017-7472)The kernel_wait4 function in kernel/exit.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service by triggering an attempted use of the -INT_MIN value.(CVE-2018-10087)The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument.(CVE-2018-10124)The xfs_dinode_verify function in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_ilock_attr_map_shared invalid pointer dereference) via a crafted xfs image.(CVE-2018-10322)The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted xfs image.(CVE-2018-10323)The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls.(CVE-2018-10675)Linux kernel is vulnerable to a stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could use this to cause a system crash and a denial of service.(CVE-2018-10880)An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls.(CVE-2018-12896)An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents.(CVE-2018-17972)An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658.(CVE-2018-18710 )An issue was discovered in the Linux kernel before 4.18.11. The ipddp_ioctl function in drivers et/appletalk/ipddp.c allows local users to obtain sensitive kernel address information by leveraging CAP_NET_ADMIN to read the ipddp_route dev and next fields via an SIOCFINDIPDDPRT ioctl call.(CVE-2018-20511)An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an __blk_drain_queue() use-after-free because a certain error case is mishandled.(CVE-2018-20856)An issue was discovered in fs/xfs/xfs_super.c in the Linux kernel before 4.18. A use after free exists, related to xfs_fs_fill_super failure.(CVE-2018-20976)Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.(CVE-2018-3693)In the function sbusfb_ioctl_helper() in drivers/video/fbdev/sbuslib.c in the Linux kernel through 4.15, an integer signedness error allows arbitrary information leakage for the FBIOPUTCMAP_SPARC and FBIOGETCMAP_SPARC commands.(CVE-2018-6412)In nfc_llcp_build_sdreq_tlv of llcp_commands.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-73083945.(CVE-2018-9518 )Insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver before version 21.10 may allow an unauthenticated user to potentially enable denial of service via adjacent access.(CVE-2019-0136)A vulnerability was found in Linux kernel

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.Security Fix(es):Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache.(CVE-2017-5754)The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access.(CVE-2017-5897)The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows 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.(CVE-2017-7261)The KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls.(CVE-2017-7472)A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.(CVE-2017-7518)The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument.(CVE-2018-10124)The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted xfs image.(CVE-2018-10323)The Linux kernel before version 4.11 is vulnerable to a NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allows an attacker controlling a CIFS server to kernel panic a client that has this server mounted, because an empty TargetInfo field in an NTLMSSP setup negotiation response is mishandled during session recovery.(CVE-2018-1066)The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls.(CVE-2018-10675)An issue was discovered in fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel through 4.17.3. An OOPS may occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp.(CVE-2018-13094)An issue was discovered in fs/xfs/xfs_super.c in the Linux kernel before 4.18. A use after free exists, related to xfs_fs_fill_super failure.(CVE-2018-20976)Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.(CVE-2018-3693)In the function sbusfb_ioctl_helper() in drivers/video/fbdev/sbuslib.c in the Linux kernel through 4.15, an integer signedness error allows arbitrary information leakage for the FBIOPUTCMAP_SPARC and FBIOGETCMAP_SPARC commands.(CVE-2018-6412)Race condition in the store_int_with_restart() function in arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel through 4.15.7 allows local users to cause a denial of service (panic) by leveraging root access to write to the check_interval file in a /sys/devices/system/machinecheck/machinecheck directory. NOTE: a third party has indicated that this report is not security relevant.(CVE-2018-7995)In the hidp_process_report in bluetooth, there is an integer overflow. This could lead to an out of bounds write with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-65853588 References: Upstream kernel.(CVE-2018-9363)In nfc_llcp_build_sdreq_tlv of llcp_commands.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-73083945.(CVE-2018-9518)A vulnerability was found in Linux kernel

    descriptionFrom Red Hat Security Advisory 2018:0151 : An update for kernel is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Note: This issue is present in hardware and cannot be fully fixed via software update. The updated kernel packages provide software mitigation for this hardware issue at a cost of potential performance penalty. Please refer to References section for further information about this issue and the performance impact. In this update initial mitigations for IBM Power (PowerPC) and IBM zSeries (S390) architectures are provided. * Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor
