Summary

cipso_v4_validate in include/net/cipso_ipv4.h in the Linux kernel before 3.11.7, when CONFIG_NETLABEL is disabled, allows attackers to cause a denial of service (infinite loop and crash), as demonstrated by icmpsic, a different vulnerability than CVE-2013-0310.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • XML Ping of the Death
    An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
  • XML Entity Expansion
    An attacker submits an XML document to a target application where the XML document uses nested entity expansion to produce an excessively large output XML. XML allows the definition of macro-like structures that can be used to simplify the creation of complex structures. However, this capability can be abused to create excessive demands on a processor's CPU and memory. A small number of nested expansions can result in an exponential growth in demands on memory.
  • Inducing Account Lockout
    An attacker leverages the security functionality of the system aimed at thwarting potential attacks to launch a denial of service attack against a legitimate system user. Many systems, for instance, implement a password throttling mechanism that locks an account after a certain number of incorrect log in attempts. An attacker can leverage this throttling mechanism to lock a legitimate user out of their own account. The weakness that is being leveraged by an attacker is the very security feature that has been put in place to counteract attacks.
  • Violating Implicit Assumptions Regarding XML Content (aka XML Denial of Service (XDoS))
    XML Denial of Service (XDoS) can be applied to any technology that utilizes XML data. This is, of course, most distributed systems technology including Java, .Net, databases, and so on. XDoS is most closely associated with web services, SOAP, and Rest, because remote service requesters can post malicious XML payloads to the service provider designed to exhaust the service provider's memory, CPU, and/or disk space. The main weakness in XDoS is that the service provider generally must inspect, parse, and validate the XML messages to determine routing, workflow, security considerations, and so on. It is exactly these inspection, parsing, and validation routines that XDoS targets. There are three primary attack vectors that XDoS can navigate Target CPU through recursion: attacker creates a recursive payload and sends to service provider Target memory through jumbo payloads: service provider uses DOM to parse XML. DOM creates in memory representation of XML document, but when document is very large (for example, north of 1 Gb) service provider host may exhaust memory trying to build memory objects. XML Ping of death: attack service provider with numerous small files that clog the system. All of the above attacks exploit the loosely coupled nature of web services, where the service provider has little to no control over the service requester and any messages the service requester sends.

    handles the basic functions of the operating system:
    memory allocation, process allocation, device input and

    rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel
    before 5.0.8. There is a race condition leading to a
    use-after-free, related to net namespace
    cleanup.(CVE-2019-11815)A flaw was found in the Linux
    kernel's handle_rx() function in the vhost_net driver.
    A malicious virtual guest, under specific conditions,
    can trigger an out-of-bounds write in a kmalloc-8 slab
    on a virtual host which may lead to a kernel memory
    corruption and a system panic. Due to the nature of the
    flaw, privilege escalation cannot be fully ruled
    out.(CVE-2018-16880)A NULL pointer dereference security
    flaw was found in the Linux kernel in kvm_pv_send_ipi()
    in arch/x86/kvm/lapic.c. This allows local users with
    certain privileges to cause a denial of service via a
    crafted system call to the KVM
    subsystem.(CVE-2018-19406)The function
    hso_get_config_data in driverset/usb/hso.c in the Linux
    kernel through 4.19.8 reads if_num from the USB device
    (as a u8) and uses it to index a small array, resulting
    in an object out-of-bounds (OOB) read that potentially
    allows arbitrary read in the kernel address
    space.(CVE-2018-19985)** RESERVED ** This candidate has
    been reserved by an organization or individual that

    organization or individual that will use it when
    announcing a new security problem. When the candidate
    has been publicized, the details for this candidate
    will be provided.(CVE-2019-3460)A flaw was found in the
    Linux kernel in the function hid_debug_events_read() in
    the drivers/hid/hid-debug.c file which may enter an
    infinite loop with certain parameters passed from a
    userspace. A local privileged user ('root') can cause a
    system lock up and a denial of
    service.(CVE-2019-3819)In the Linux kernel before
    4.20.14, expand_downwards in mm/mmap.c lacks a check
    for the mmap minimum address, which makes it easier for
    attackers to exploit kernel NULL pointer dereferences
    on non-SMAP platforms. This is related to a capability
    check for the wrong task.(CVE-2019-9213)A flaw was
    found in the Linux kernel's vfio interface
    implementation that permits violation of the user's
    locked memory limit. If a device is bound to a vfio
    driver, such as vfio-pci, and the local attacker is
    administratively granted ownership of the device, it
    may cause a system memory exhaustion and thus a denial
    of service (DoS). Versions 3.10, 4.14 and 4.18 are
    vulnerable.(CVE-2019-3882)An infinite loop issue was
    found in the vhost_net kernel module in Linux Kernel up
    to and including v5.1-rc6, while handling incoming
    packets in handle_rx(). It could occur if one end sends
    packets faster than the other end can process them. A
    guest user, maybe remote one, could use this flaw to
    stall the vhost_net kernel thread, resulting in a DoS
    scenario.(CVE-2019-3900)It was found that the net_dma
    code in tcp_recvmsg() in the 2.6.32 kernel as shipped
    in RHEL6 is thread-unsafe. So an unprivileged
    multi-threaded userspace application calling recvmsg()
    for the same network socket in parallel executed on
    ioatdma-enabled hardware with net_dma enabled can leak
    the memory, crash the host leading to a
    denial-of-service or cause a random memory
    corruption.(CVE-2019-3837)A race condition in
    perf_event_open() allows local attackers to leak
    sensitive data from setuid programs. As no relevant
    locks (in particular the cred_guard_mutex) are held
    during the ptrace_may_access() call, it is possible for
    the specified target task to perform an execve()
    syscall with setuid execution before perf_event_alloc()
    actually attaches to it, allowing an attacker to bypass
    the ptrace_may_access() check and the
    perf_event_exit_task(current) call that is performed in
    install_exec_creds() during privileged execve() calls.
    This issue affects kernel versions before 4.8.

    includeet/cipso_ipv4.h in the Linux kernel before
    3.11.7, when CONFIG_NETLABEL is disabled, allows
    attackers to cause a denial of service (infinite loop
    and crash), as demonstrated by icmpsic, a different
    vulnerability than CVE-2013-0310.(CVE-2013-7470)Note1:
    kernel-4.19.36-vhulk1907.1.0.h529 and earlier versions
    in EulerOS Virtualization for ARM 64 3.0.2.0 return
