Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

  - Memory leak in drivers/media/video/videobuf-core.c in
    the videobuf subsystem in the Linux kernel 2.6.x
    through 4.x allows local users to cause a denial of
    service (memory consumption) by leveraging /dev/video

    announcing a new security problem. When the candidate
    has been publicized, the details for this candidate
    will be provided.(CVE-2018-1108i1/4%0

  - The KVM implementation in the Linux kernel through
    4.20.5 has an Information Leak.(CVE-2019-7222i1/4%0

  - The adreno_perfcounter_query_group function in
    drivers/gpu/msm/adreno_perfcounter.c in the Adreno GPU
    driver for the Linux kernel 3.x, as used in Qualcomm
    Innovation Center (QuIC) Android contributions for MSM
    devices and other products, uses an incorrect integer
    data type, which allows attackers to cause a denial of
    service (integer overflow, heap-based buffer overflow,
    and incorrect memory allocation) or possibly have
    unspecified other impact via a crafted
    IOCTL_KGSL_PERFCOUNTER_QUERY ioctl
    call.(CVE-2016-2062i1/4%0

  - drivers/hid/hid-ntrig.c in the Human Interface Device
    (HID) subsystem in the Linux kernel through 3.11, when
    CONFIG_HID_NTRIG is enabled, allows physically
    proximate attackers to cause a denial of service (NULL
    pointer dereference and OOPS) via a crafted
    device.(CVE-2013-2896i1/4%0

  - 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-2016-3139i1/4%0

  - An integer overflow vulnerability in
    ip6_find_1stfragopt() function was found. A local
    attacker that has privileges (of CAP_NET_RAW) to open
    raw socket can cause an infinite loop inside the
    ip6_find_1stfragopt() function.(CVE-2017-7542i1/4%0

  - Memory leak in the virtio_gpu_object_create function in
    drivers/gpu/drm/virtio/virtgpu_object.c in the Linux
    kernel through 4.11.8 allows attackers to cause a
    denial of service (memory consumption) by triggering
    object-initialization failures.(CVE-2017-10810i1/4%0

  - The ping_recvmsg function in net/ipv4/ping.c in the
    Linux kernel before 3.12.4 does not properly interact
    with read system calls on ping sockets, which allows
    local users to cause a denial of service (NULL pointer
    dereference and system crash) by leveraging unspecified
    privileges to execute a crafted
    application.(CVE-2013-6432i1/4%0

  - The madvise_willneed function in the Linux kernel
    allows local users to cause a denial of service
    (infinite loop) by triggering use of MADVISE_WILLNEED
    for a DAX mapping.(CVE-2017-18208i1/4%0

  - An issue was discovered in the Linux kernel through
    4.18.8. The vmacache_flush_all function in
    mm/vmacache.c mishandles sequence number overflows. An
    attacker can trigger a use-after-free (and possibly
    gain privileges) via certain thread creation, map,
    unmap, invalidation, and dereference
    operations.(CVE-2018-17182i1/4%0

  - The ieee80211_radiotap_iterator_init function in
    net/wireless/radiotap.c in the Linux kernel before
    3.11.7 does not check whether a frame contains any data
    outside of the header, which might allow attackers to
    cause a denial of service (buffer over-read) via a
    crafted header.(CVE-2013-7027i1/4%0

  - The Btrfs implementation in the Linux kernel before
    3.19 does not ensure that the visible xattr state is
    consistent with a requested replacement, which allows
    local users to bypass intended ACL settings and gain
    privileges via standard filesystem operations (1)
    during an xattr-replacement time window, related to a
    race condition, or (2) after an xattr-replacement
    attempt that fails because the data does not
    fit.(CVE-2014-9710i1/4%0

  - A flaw was found in the way the Linux kernel's Stream
    Control Transmission Protocol (SCTP) implementation
    handled duplicate Address Configuration Change Chunks
    (ASCONF). A remote attacker could use either of these
    flaws to crash the system.(CVE-2014-3687i1/4%0

  - A syntax vulnerability was discovered in the kernel's
    ASN1.1 DER decoder, which could lead to memory
    corruption or a complete local denial of service
    through x509 certificate DER files. A local system user
    could use a specially created key file to trigger
    BUG_ON() in the public_key_verify_signature() function
    (crypto/asymmetric_keys/public_key.c), to cause a
    kernel panic and crash the system.(CVE-2016-2053i1/4%0

  - It was found that the Linux kernel's KVM subsystem did
    not handle the VM exits gracefully for the invept
    (Invalidate Translations Derived from EPT)
    instructions. On hosts with an Intel processor and
    invept VM exit support, an unprivileged guest user
    could use these instructions to crash the
    guest.(CVE-2014-3645i1/4%0

  - The packet_recvmsg function in net/packet/af_packet.c
    in the Linux kernel before 3.12.4 updates a certain
    length value before ensuring that an associated data
    structure has been initialized, which allows local
    users to obtain sensitive information from kernel
    memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg
    system call.(CVE-2013-7270i1/4%0

  - The init_new_context function in
    arch/x86/include/asm/mmu_context.h in the Linux kernel,
    before 4.12.10, does not correctly handle errors from
    LDT table allocation when forking a new process. This
    could allow a local attacker to achieve a
    use-after-free or possibly have unspecified other
    impact by running a specially crafted
    program.(CVE-2017-17053i1/4%0

  - It was found that the sanity_check_raw_super() function
    in 'fs/f2fs/super.c' file in the Linux kernel before
    version 4.12-rc1 does not validate the f2fs filesystem
    segment count. This allows an unprivileged local user
    to cause a system panic and DoS. Due to the nature of
    the flaw, privilege escalation cannot be fully ruled
    out, although we believe it is
    unlikely.(CVE-2017-10662i1/4%0
