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.

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

  - CVE-2017-7518
    Andy Lutomirski discovered that KVM is prone to an
    incorrect debug exception (#DB) error occurring while
    emulating a syscall instruction. A process inside a
    guest can take advantage of this flaw for privilege
    escalation inside a guest.

  - CVE-2017-7558 (stretch only)
    Stefano Brivio of Red Hat discovered that the SCTP
    subsystem is prone to a data leak vulnerability due to
    an out-of-bounds read flaw, allowing to leak up to 100
    uninitialized bytes to userspace.

  - CVE-2017-10661 (jessie only)
    Dmitry Vyukov of Google reported that the timerfd
    facility does not properly handle certain concurrent
    operations on a single file descriptor. This allows a
    local attacker to cause a denial of service or
    potentially execute arbitrary code.

  - CVE-2017-11600
    Bo Zhang reported that the xfrm subsystem does not
    properly validate one of the parameters to a netlink
    message. Local users with the CAP_NET_ADMIN capability
    can use this to cause a denial of service or potentially
    to execute arbitrary code.

  - CVE-2017-12134 / #866511 / XSA-229
    Jan H. Schoenherr of Amazon discovered that when Linux
    is running in a Xen PV domain on an x86 system, it may
    incorrectly merge block I/O requests. A buggy or
    malicious guest may trigger this bug in dom0 or a PV
    driver domain, causing a denial of service or
    potentially execution of arbitrary code.

  This issue can be mitigated by disabling merges on the underlying
  back-end block devices, e.g.:echo 2 >
  /sys/block/nvme0n1/queue/nomerges

  - CVE-2017-12146 (stretch only)
    Adrian Salido of Google reported a race condition in
    access to the'driver_override' attribute for platform
    devices in sysfs. If unprivileged users are permitted to
    access this attribute, this might allow them to gain
    privileges.

  - CVE-2017-12153
    Bo Zhang reported that the cfg80211 (wifi) subsystem
    does not properly validate the parameters to a netlink
    message. Local users with the CAP_NET_ADMIN capability
    (in any user namespace with a wifi device) can use this
    to cause a denial of service.

  - CVE-2017-12154
    Jim Mattson of Google reported that the KVM
    implementation for Intel x86 processors did not
    correctly handle certain nested hypervisor
    configurations. A malicious guest (or nested guest in a
    suitable L1 hypervisor) could use this for denial of
    service.

  - CVE-2017-14106
    Andrey Konovalov discovered that a user-triggerable
    division by zero in the tcp_disconnect() function could
    result in local denial of service.

  - CVE-2017-14140
    Otto Ebeling reported that the move_pages() system call
    performed insufficient validation of the UIDs of the
    calling and target processes, resulting in a partial
    ASLR bypass. This made it easier for local users to
    exploit vulnerabilities in programs installed with the
    set-UID permission bit set.

  - CVE-2017-14156
    'sohu0106' reported an information leak in the atyfb
    video driver. A local user with access to a framebuffer
    device handled by this driver could use this to obtain
    sensitive information.

  - CVE-2017-14340
    Richard Wareing discovered that the XFS implementation
    allows the creation of files with the 'realtime' flag on
    a filesystem with no realtime device, which can result
    in a crash (oops). A local user with access to an XFS
    filesystem that does not have a realtime device can use
    this for denial of service.

  - CVE-2017-14489
    ChunYu Wang of Red Hat discovered that the iSCSI
    subsystem does not properly validate the length of a
    netlink message, leading to memory corruption. A local
    user with permission to manage iSCSI devices can use
    this for denial of service or possibly to execute
    arbitrary code.

  - CVE-2017-14497 (stretch only)
    Benjamin Poirier of SUSE reported that vnet headers are
    not properly handled within the tpacket_rcv() function
    in the raw packet (af_packet) feature. A local user with
    the CAP_NET_RAW capability can take advantage of this
    flaw to cause a denial of service (buffer overflow, and
    disk and memory corruption) or have other impact.

  - CVE-2017-1000111
    Andrey Konovalov of Google reported a race condition in
    the raw packet (af_packet) feature. Local users with the
    CAP_NET_RAW capability can use this for denial of
    service or possibly to execute arbitrary code.

  - CVE-2017-1000112
    Andrey Konovalov of Google reported a race condition
    flaw in the UDP Fragmentation Offload (UFO) code. A
    local user can use this flaw for denial of service or
    possibly to execute arbitrary code.

  - CVE-2017-1000251 / #875881
    Armis Labs discovered that the Bluetooth subsystem does
    not properly validate L2CAP configuration responses,
    leading to a stack-based buffer overflow. This is one of
    several vulnerabilities dubbed 'Blueborne'. A nearby
    attacker can use this to cause a denial of service or
    possibly to execute arbitrary code on a system with
    Bluetooth enabled.

  - CVE-2017-1000252 (stretch only)
    Jan H. Schoenherr of Amazon reported that the KVM
    implementation for Intel x86 processors did not
    correctly validate interrupt injection requests. A local
    user with permission to use KVM could use this for
    denial of service.

  - CVE-2017-1000370
    The Qualys Research Labs reported that a large argument
    or environment list can result in ASLR bypass for 32-bit
    PIE binaries.

  - CVE-2017-1000371
    The Qualys Research Labs reported that a large argument
    or environment list can result in a stack/heap clash for
    32-bit PIE binaries.

  - CVE-2017-1000380
    Alexander Potapenko of Google reported a race condition
    in the ALSA (sound) timer driver, leading to an
    information leak. A local user with permission to access
    sound devices could use this to obtain sensitive
    information.

Debian disables unprivileged user namespaces by default, but if they
are enabled (via the kernel.unprivileged_userns_clone sysctl) then
CVE-2017-11600, CVE-2017-14497 and CVE-2017-1000111 can be exploited
by any local user."

    NASL idSUSE_SU-2018-0040-1.NASL
    descriptionThe SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes.

"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

  - 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 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

    have unspecified other impact via a crafted USB device
    (bnc#1066606).

  - CVE-2017-16527: sound/usb/mixer.c in the Linux kernel
    allowed local users to cause a denial of service
    (snd_usb_mixer_interrupt use-after-free and system
    crash) or possibly have unspecified other impact via a
    crafted USB device (bnc#1066625).

  - 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).

  - 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-2017-15265: Race condition in the ALSA subsystem in
    the Linux kernel allowed local users to cause a denial
    of service (use-after-free) or possibly have unspecified
    other impact via crafted /dev/snd/seq ioctl calls,
    related to sound/core/seq/seq_clientmgr.c and
    sound/core/seq/seq_ports.c (bnc#1062520).

  - CVE-2017-14489: The iscsi_if_rx function in
    drivers/scsi/scsi_transport_iscsi.c in the Linux kernel
    allowed local users to cause a denial of service (panic)
    by leveraging incorrect length validation (bnc#1059051).

  - CVE-2017-14340: The XFS_IS_REALTIME_INODE macro in
    fs/xfs/xfs_linux.h in the Linux kernel did not verify
    that a filesystem has a realtime device, which allowed
    local users to cause a denial of service (NULL pointer
    dereference and OOPS) via vectors related to setting an
    RHINHERIT flag on a directory (bnc#1058524).

  - CVE-2017-14140: The move_pages system call in
    mm/migrate.c in the Linux kernel doesn't check the
    effective uid of the target process, enabling a local
    attacker to learn the memory layout of a setuid
    executable despite ASLR (bnc#1057179).

  - 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-2017-10661: 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-2017-12762: 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-2017-8831: The saa7164_bus_get function in
    drivers/media/pci/saa7164/saa7164-bus.c in the Linux
    kernel allowed local users to cause a denial of service
    (out-of-bounds array access) or possibly have
    unspecified other impact by changing a certain
    sequence-number value, aka a 'double fetch'
    vulnerability (bnc#1037994).

  - CVE-2017-1000112: An exploitable memory corruption due
    to UFO to non-UFO path switch was fixed. (bnc#1052311
    bnc#1052365).

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-7482 Shi Lei discovered that RxRPC Kerberos 5 ticket handling code does not properly verify metadata, leading to information disclosure, denial of service or potentially execution of arbitrary code. CVE-2017-7542 An integer overflow vulnerability in the ip6_find_1stfragopt() function was found allowing a local attacker with privileges to open raw sockets to cause a denial of service. CVE-2017-7889 Tommi Rantala and Brad Spengler reported that the mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, allowing a local attacker with access to /dev/mem to obtain sensitive information or potentially execute arbitrary code. CVE-2017-10661 Dmitry Vyukov of Google reported that the timerfd facility does not properly handle certain concurrent operations on a single file descriptor. This allows a local attacker to cause a denial of service or potentially to execute arbitrary code. CVE-2017-10911 / XSA-216 Anthony Perard of Citrix discovered an information leak flaw in Xen blkif response handling, allowing a malicious unprivileged guest to obtain sensitive information from the host or other guests. CVE-2017-11176 It was discovered that the mq_notify() function does not set the sock pointer to NULL upon entry into the retry logic. An attacker can take advantage of this flaw during a userspace close of a Netlink socket to cause a denial of service or potentially cause other impact. CVE-2017-11600 bo Zhang reported that the xfrm subsystem does not properly validate one of the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability can use this to cause a denial of service or potentially to execute arbitrary code. CVE-2017-12134 / #866511 / XSA-229 Jan H. Sch&ouml;nherr of Amazon discovered that when Linux is running in a Xen PV domain on an x86 system, it may incorrectly merge block I/O requests. A buggy or malicious guest may trigger this bug in dom0 or a PV driver domain, causing a denial of service or potentially execution of arbitrary code. This issue can be mitigated by disabling merges on the underlying back-end block devices, e.g.: echo 2 > /sys/block/nvme0n1/queue/nomerges CVE-2017-12153 bo Zhang reported that the cfg80211 (wifi) subsystem does not properly validate the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability on a system with a wifi device can use this to cause a denial of service. CVE-2017-12154 Jim Mattson of Google reported that the KVM implementation for Intel x86 processors did not correctly handle certain nested hypervisor configurations. A malicious guest (or nested guest in a suitable L1 hypervisor) could use this for denial of service. CVE-2017-14106 Andrey Konovalov of Google reported that a specific sequence of operations on a TCP socket could lead to division by zero. A local user could use this for denial of service. CVE-2017-14140 Otto Ebeling reported that the move_pages() system call permitted users to discover the memory layout of a set-UID process running under their real user-ID. This made it easier for local users to exploit vulnerabilities in programs installed with the set-UID permission bit set. CVE-2017-14156

    descriptionUSN-3444-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. Jan H. Schonherr discovered that the Xen subsystem did not properly handle block IO merges correctly in some situations. An attacker in a guest vm could use this to cause a denial of service (host crash) or possibly gain administrative privileges in the host. (CVE-2017-12134) Andrey Konovalov discovered that a divide-by-zero error existed in the TCP stack implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-14106) Otto Ebeling discovered that the memory manager in the Linux kernel did not properly check the effective UID in some situations. A local attacker could use this to expose sensitive information. (CVE-2017-14140). 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.
