Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leveraging Race Conditions
    This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
  • Leveraging Race Conditions via Symbolic Links
    This attack leverages the use of symbolic links (Symlinks) in order to write to sensitive files. An attacker can create a Symlink link to a target file not otherwise accessible to her. When the privileged program tries to create a temporary file with the same name as the Symlink link, it will actually write to the target file pointed to by the attackers' Symlink link. If the attacker can insert malicious content in the temporary file she will be writing to the sensitive file by using the Symlink. The race occurs because the system checks if the temporary file exists, then creates the file. The attacker would typically create the Symlink during the interval between the check and the creation of the temporary file.

VM could possibly use this to cause a denial of service in the host
system. (CVE-2019-3900)

Daniele Antonioli, Nils Ole Tippenhauer, and Kasper B. Rasmussen
discovered that the Bluetooth protocol BR/EDR specification did not
properly require sufficiently strong encryption key lengths. A
physicall proximate attacker could use this to expose sensitive
information. (CVE-2019-9506)

It was discovered that the Appletalk IP encapsulation driver in the
Linux kernel did not properly prevent kernel addresses from being
copied to user space. A local attacker with the CAP_NET_ADMIN
capability could use this to expose sensitive information.
(CVE-2018-20511)

It was discovered that a race condition existed in the USB YUREX
device driver in the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (system crash).
(CVE-2019-15216)

It was discovered that the Siano USB MDTV receiver device driver in
the Linux kernel made improper assumptions about the device
characteristics. A physically proximate attacker could use this cause
a denial of service (system crash). (CVE-2019-15218)

It was discovered that the Line 6 POD USB device driver in the Linux
kernel did not properly validate data size information from the
device. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2019-15221)

Muyu Yu discovered that the CAN implementation in the Linux kernel in
some situations did not properly restrict the field size when
processing outgoing frames. A local attacker with CAP_NET_ADMIN
privileges could use this to execute arbitrary code. (CVE-2019-3701)

Vladis Dronov discovered that the debug interface for the Linux
kernel's HID subsystem did not properly validate passed parameters in
some situations. A local privileged attacker could use this to cause a
denial of service (infinite loop). (CVE-2019-3819).

  script_set_attribute(attribute:"description", value:
"According to the versions of the kernel packages installed, the
EulerOS Virtualization for ARM 64 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):A flaw was found in the
    Linux kernel's NFS implementation, all versions 3.x and
    all versions 4.x up to 4.20. An attacker, who is able
    to mount an exported NFS filesystem, is able to trigger
    a null pointer dereference by using an invalid NFS
    sequence. This can panic the machine and deny access to
    the NFS server. Any outstanding disk writes to the NFS
    server will be lost.(CVE-2018-16871)An issue was
    discovered in the Linux kernel before 4.18.7. In
    create_qp_common in drivers/infiniband/hw/mlx5/qp.c,
    mlx5_ib_create_qp_resp was never initialized, resulting
    in a leak of stack memory to
    userspace.(CVE-2018-20855)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)The
    Linux kernel 4.x (starting from 4.1) and 5.x before
    5.0.8 allows Information Exposure (partial kernel
    address disclosure), leading to a KASLR bypass.
    Specifically, it is possible to extract the KASLR
    kernel image offset using the IP ID values the kernel
    produces for connection-less protocols (e.g., UDP and
    ICMP). When such traffic is sent to multiple
    destination IP addresses, it is possible to obtain hash
    collisions (of indices to the counter array) and
    thereby obtain the hashing key (via enumeration). This
    key contains enough bits from a kernel address (of a
    static variable) so when the key is extracted (via
    enumeration), the offset of the kernel image is
    exposed. This attack can be carried out remotely, by
    the attacker forcing the target device to send UDP or
    ICMP (or certain other) traffic to attacker-controlled
    IP addresses. Forcing a server to send UDP traffic is
    trivial if the server is a DNS server. ICMP traffic is
    trivial if the server answers ICMP Echo requests
    (ping). For client targets, if the target visits the
    attacker's web page, then WebRTC or gQUIC can be used
    to force UDP traffic to attacker-controlled IP
    addresses. NOTE: this attack against KASLR became
    viable in 4.1 because IP ID generation was changed to
    have a dependency on an address associated with a
    network namespace.(CVE-2019-10639)** DISPUTED ** An
    issue was discovered in ip6_ra_control in
    net/ipv6/ipv6_sockglue.c in the Linux kernel through
    5.1.5. There is an unchecked kmalloc of new_ra, which
    might allow an attacker to cause a denial of service
    (NULL pointer dereference and system crash). NOTE: This
    has been disputed as not an
    issue.(CVE-2019-12378)**DISPUTED** An issue was
    discovered in the efi subsystem in the Linux kernel
    through 5.1.5. phys_efi_set_virtual_address_map in
    arch/x86/platform/efi/efi.c and efi_call_phys_prolog in
    arch/x86/platform/efi/efi_64.c mishandle memory
    allocation failures. NOTE: This id is disputed as not
    being an issue because ?All the code touched by the
    referenced commit runs only at boot, before any user
    processes are started. Therefore, there is no
    possibility for an unprivileged user to control
    it.?.(CVE-2019-12380)** DISPUTED ** An issue was
    discovered in ip_ra_control in net/ipv4/ip_sockglue.c
    in the Linux kernel through 5.1.5. There is an
    unchecked kmalloc of new_ra, which might allow an
    attacker to cause a denial of service (NULL pointer
    dereference and system crash). NOTE: this is disputed
    because new_ra is never used if it is
    NULL.(CVE-2019-12381)** DISPUTED ** An issue was
    discovered in the MPT3COMMAND case in _ctl_ioctl_main
    in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux
    kernel through 5.1.5. It allows local users to cause a
    denial of service or possibly have unspecified other
    impact by changing the value of ioc_number between two
    kernel reads of that value, aka a 'double fetch'
    vulnerability. NOTE: a third party reports that this is
    unexploitable because the doubly fetched value is not
    used.(CVE-2019-12456)An issue was discovered in the
    Linux kernel before 4.20.15. The nfc_llcp_build_tlv
    function in net/nfc/llcp_commands.c may return NULL. If
    the caller does not check for this, it will trigger a
    NULL pointer dereference. This will cause denial of
    service. This affects nfc_llcp_build_gb in
    net/nfc/llcp_core.c.(CVE-2019-12818)An issue was
    discovered in the Linux kernel before 5.0. The function
    __mdiobus_register() in drivers/net/phy/mdio_bus.c
    calls put_device(), which will trigger a
    fixed_mdio_bus_init use-after-free. This will cause a
    denial of service.(CVE-2019-12819)A NULL pointer
    dereference vulnerability in the function
    nfc_genl_deactivate_target() in net/nfc/netlink.c in
    the Linux kernel before 5.1.13 can be triggered by a
    malicious user-mode program that omits certain NFC
    attributes, leading to denial of
    service.(CVE-2019-12984)In the Linux kernel before
    5.1.17, ptrace_link in kernel/ptrace.c mishandles the
    recording of the credentials of a process that wants to
    create a ptrace relationship, which allows local users
    to obtain root access by leveraging certain scenarios
    with a parent-child process relationship, where a
    parent drops privileges and calls execve (potentially
    allowing control by an attacker). One contributing
    factor is an object lifetime issue (which can also
    cause a panic). Another contributing factor is
    incorrect marking of a ptrace relationship as
    privileged, which is exploitable through (for example)
    Polkit's pkexec helper with PTRACE_TRACEME. NOTE:
    SELinux deny_ptrace might be a usable workaround in
    some environments.(CVE-2019-13272)In
    parse_hid_report_descriptor in
    drivers/input/tablet/gtco.c in the Linux kernel through
    5.2.1, a malicious USB device can send an HID report
    that triggers an out-of-bounds write during generation
    of debugging messages.(CVE-2019-13631)In the Linux
    kernel through 5.2.1 on the powerpc platform, when
    hardware transactional memory is disabled, a local user
    can cause a denial of service (TM Bad Thing exception
    and system crash) via a sigreturn() system call that
    sends a crafted signal frame. This affects
    arch/powerpc/kernel/signal_32.c and
    arch/powerpc/kernel/signal_64.c.(CVE-2019-13648)In the
    Linux kernel before 5.2.3, set_geometry in
    drivers/block/floppy.c does not validate the sect and
    head fields, as demonstrated by an integer overflow and
    out-of-bounds read. It can be triggered by an
    unprivileged local user when a floppy disk has been
    inserted. NOTE: QEMU creates the floppy device by
    default.(CVE-2019-14283)In the Linux kernel before
    5.2.3, drivers/block/floppy.c allows a denial of
    service by setup_format_params division-by-zero. Two
    consecutive ioctls can trigger the bug: the first one
    should set the drive geometry with .sect and .rate
    values that make F_SECT_PER_TRACK be zero. Next, the
    floppy format operation should be called. It can be
    triggered by an unprivileged local user even when a
    floppy disk has not been inserted. NOTE: QEMU creates
    the floppy device by default.(CVE-2019-14284)In the
    Linux kernel before 4.16.4, a double-locking error in
    drivers/usb/dwc3/gadget.c may potentially cause a
    deadlock with f_hid.(CVE-2019-14763)An issue was
    discovered in the Linux kernel before 5.2.6. There is a
    use-after-free caused by a malicious USB device in the
    drivers/media/v4l2-core/v4l2-dev.c driver because
    drivers/media/radio/radio-raremono.c does not properly
    allocate memory.(CVE-2019-15211)An issue was discovered
    in the Linux kernel before 5.0.9. There is a
    use-after-free in atalk_proc_exit, related to
    net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and
    net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)Note:
    kernel-4.19.36-vhulk1907.1.0.h529 and earlier versions
    in EulerOS Virtualization for ARM 64 3.0.2.0 return
    incorrect time information when executing the uname -a
    command.

    descriptionUSN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update, a regression was introduced that caused a kernel crash when handling fragmented packets in some situations. This update addresses the issue. We apologize for the inconvenience. Original advisory details : Hui Peng and Mathias Payer discovered that the Option USB High Speed driver in the Linux kernel did not properly validate metadata received from the device. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2018-19985) Zhipeng Xie discovered that an infinite loop could triggered in the CFS Linux kernel process scheduler. A local attacker could possibly use this to cause a denial of service. (CVE-2018-20784) It was discovered that the Intel Wi-Fi device driver in the Linux kernel did not properly validate certain Tunneled Direct Link Setup (TDLS). A physically proximate attacker could use this to cause a denial of service (Wi-Fi disconnect). (CVE-2019-0136) It was discovered that the Bluetooth UART implementation in the Linux kernel did not properly check for missing tty operations. A local attacker could use this to cause a denial of service. (CVE-2019-10207) Amit Klein and Benny Pinkas discovered that the Linux kernel did not sufficiently randomize IP ID values generated for connectionless networking protocols. A remote attacker could use this to track particular Linux devices. (CVE-2019-10638) Amit Klein and Benny Pinkas discovered that the location of kernel addresses could be exposed by the implementation of connection-less network protocols in the Linux kernel. A remote attacker could possibly use this to assist in the exploitation of another vulnerability in the Linux kernel. (CVE-2019-10639) It was discovered that an integer overflow existed in the Linux kernel when reference counting pages, leading to potential use-after-free issues. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-11487) Jann Horn discovered that a race condition existed in the Linux kernel when performing core dumps. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2019-11599) It was discovered that a NULL pointer dereference vulnerability existed in the LSI Logic MegaRAID driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-11810) It was discovered that the GTCO tablet input driver in the Linux kernel did not properly bounds check the initial HID report sent by the device. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-13631) Praveen Pandey discovered that the Linux kernel did not properly validate sent signals in some situations on PowerPC systems with transactional memory disabled. A local attacker could use this to cause a denial of service. (CVE-2019-13648) It was discovered that the floppy driver in the Linux kernel did not properly validate meta data, leading to a buffer overread. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-14283) It was discovered that the floppy driver in the Linux kernel did not properly validate ioctl() calls, leading to a division-by-zero. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-14284) Tuba Yavuz discovered that a race condition existed in the DesignWare USB3 DRD Controller device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service. (CVE-2019-14763) It was discovered that an out-of-bounds read existed in the QLogic QEDI iSCSI Initiator Driver in the Linux kernel. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2019-15090) It was discovered that the Raremono AM/FM/SW radio device driver in the Linux kernel did not properly allocate memory, leading to a use-after-free. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2019-15211) It was discovered at a double-free error existed in the USB Rio 500 device driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service. (CVE-2019-15212) It was discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel, leading to a potential use-after-free. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-15214) It was discovered that a race condition existed in the CPiA2 video4linux device driver for the Linux kernel, leading to a use-after-free. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-15215) It was discovered that a race condition existed in the Softmac USB Prism54 device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15220) It was discovered that a use-after-free vulnerability existed in the AppleTalk implementation in the Linux kernel if an error occurs during initialization. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-15292) Jason Wang discovered that an infinite loop vulnerability existed in the virtio net driver in the Linux kernel. A local attacker in a guest VM could possibly use this to cause a denial of service in the host system. (CVE-2019-3900) Daniele Antonioli, Nils Ole Tippenhauer, and Kasper B. Rasmussen discovered that the Bluetooth protocol BR/EDR specification did not properly require sufficiently strong encryption key lengths. A physically proximate attacker could use this to expose sensitive information. (CVE-2019-9506) It was discovered that a race condition existed in the USB YUREX device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15216) It was discovered that the Siano USB MDTV receiver device driver in the Linux kernel made improper assumptions about the device characteristics. A physically proximate attacker could use this cause a denial of service (system crash). (CVE-2019-15218) It was discovered that the Line 6 POD USB device driver in the Linux kernel did not properly validate data size information from the device. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15221) Muyu Yu discovered that the CAN implementation in the Linux kernel in some situations did not properly restrict the field size when processing outgoing frames. A local attacker with CAP_NET_ADMIN privileges could use this to execute arbitrary code. (CVE-2019-3701) Vladis Dronov discovered that the debug interface for the Linux kernel
