Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

    "According to the versions of the libxml2 packages installed, the
    EulerOS installation on the remote host is affected by the following
    vulnerabilities :
    
      - dict.c in libxml2 allows remote attackers to cause a
        denial of service (heap-based buffer over-read and
        application crash) via an unexpected character
        immediately after the '<!DOCTYPE html' substring in a
        crafted HTML document.(CVE-2015-8806)
    
      - libxml2 2.9.4, when used in recover mode, allows remote
        attackers to cause a denial of service (NULL pointer
        dereference) via a crafted XML document. NOTE: The
        maintainer states 'I would disagree of a CVE with the
        Recover parsing option which should only be used for
        manual recovery at least for XML
        parser.'(CVE-2017-5969)
    
      - The htmlParseTryOrFinish function in HTMLparser.c in
        libxml2 2.9.4 allows attackers to cause a denial of
        service (buffer over-read) or information
        disclosure.(CVE-2017-8872)
    
      - libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a
        stack-based buffer overflow. The function
        xmlSnprintfElementContent in valid.c is supposed to
        recursively dump the element content definition into a
        char buffer 'buf' of size 'size'. At the end of the
        routine, the function may strcat two more characters
        without checking whether the current strlen(buf) + 2 <
        size. This vulnerability causes programs that use
        libxml2, such as PHP, to crash.(CVE-2017-9048)
    
      - libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a
        heap-based buffer over-read in the
        xmlDictComputeFastKey function in dict.c. This
        vulnerability causes programs that use libxml2, such as
        PHP, to crash. This vulnerability exists because of an
        incomplete fix for libxml2 Bug 759398.(CVE-2017-9049)
    
      - libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a
        heap-based buffer over-read in the xmlDictAddString
        function in dict.c. This vulnerability causes programs

        vulnerability exists because of an incomplete fix for
        CVE-2016-1839.(CVE-2017-9050)
    
      - The xz_decomp function in xzlib.c in libxml2 2.9.8, if
        --with-lzma is used, allows remote attackers to cause a
        denial of service (infinite loop) via a crafted XML
        file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated
        by xmllint, a different vulnerability than

    The htmlParseTryOrFinish function in HTMLparser.c in libxml2 2.9.4
    allows attackers to cause a denial of service (buffer over-read) or
    information disclosure.
    
    A buffer overflow was discovered in libxml2
    20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in
    valid.c is supposed to recursively dump the element content definition
    into a char buffer 'buf' of size 'size'. The variable len is assigned
    strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then
    (i) the content->prefix is appended to buf (if it actually fits)
    whereupon (ii) content->name is written to the buffer. However, the
    check for whether the content->name actually fits also uses 'len'
    rather than the updated buffer length strlen(buf). This allows us to
    write about 'size' many bytes beyond the allocated memory. This
    vulnerability causes programs that use libxml2, such as PHP, to crash.
    
    libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based
    buffer overflow. The function xmlSnprintfElementContent in valid.c is
    supposed to recursively dump the element content definition into a
    char buffer 'buf' of size 'size'. At the end of the routine, the
    function may strcat two more characters without checking whether the
    current strlen(buf) + 2 < size. This vulnerability causes programs
    that use libxml2, such as PHP, to crash.
    
    libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based
    buffer over-read in the xmlDictComputeFastKey function in dict.c. This
    vulnerability causes programs that use libxml2, such as PHP, to crash.
    This vulnerability exists because of an incomplete fix for libxml2 Bug
    759398.
