"According to the versions of the libarchive package installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - The read_Header function in
    archive_read_support_format_7zip.c in libarchive 3.2.1
    allows remote attackers to cause a denial of service
    (out-of-bounds read) via multiple EmptyStream
    attributes in a header in a 7zip
    archive.(CVE-2016-8689)

  - Stack-based buffer overflow in the safe_fprintf
    function in tar/util.c in libarchive 3.2.1 allows
    remote attackers to cause a denial of service via a
    crafted non-printable multibyte character in a
    filename.(CVE-2016-8687)

  - libarchive 3.3.2 suffers from an out-of-bounds read
    within lha_read_data_none() in
    archive_read_support_format_lha.c when extracting a
    specially crafted lha archive, related to
    lha_crc16.(CVE-2017-14503)

  - An out-of-bounds read flaw exists in parse_file_info in
    archive_read_support_format_iso9660.c in libarchive
    3.3.2 when extracting a specially crafted iso9660 iso
    file, related to
    archive_read_format_iso9660_read_header.(CVE-2017-14501
    )

  - libarchive 3.3.2 allows remote attackers to cause a
    denial of service (xml_data heap-based buffer over-read
    and application crash) via a crafted xar archive,
    related to the mishandling of empty strings in the
    atol8 function in
    archive_read_support_format_xar.c.(CVE-2017-14166)

  - The mtree bidder in libarchive 3.2.1 does not keep
    track of line sizes when extending the read-ahead,
    which allows remote attackers to cause a denial of
    service (crash) via a crafted file, which triggers an
    invalid read in the (1) detect_form or (2) bid_entry
    function in
    libarchive/archive_read_support_format_mtree.c.(CVE-201
    6-8688)

  - The archive_read_format_cab_read_header function in
    archive_read_support_format_cab.c in libarchive 3.2.2
    allows remote attackers to cause a denial of service
    (heap-based buffer over-read and application crash) via
    a crafted file.(CVE-2016-10350)

  - The archive_le32dec function in archive_endian.h in
    libarchive 3.2.2 allows remote attackers to cause a
    denial of service (heap-based buffer over-read and
    application crash) via a crafted file.(CVE-2016-10349)

  - The archive_wstring_append_from_mbs function in
    archive_string.c in libarchive 3.2.2 allows remote
    attackers to cause a denial of service (NULL pointer
    dereference and application crash) via a crafted
    archive file.(CVE-2016-10209)

  - Integer overflow in the archive_read_format_tar_skip
    function in archive_read_support_format_tar.c in
    libarchive before 3.2.0 allows remote attackers to
    cause a denial of service (crash) via a crafted tar
    file.(CVE-2015-8933)

  - bsdcpio in libarchive before 3.2.0 allows remote
    attackers to cause a denial of service (invalid read
    and crash) via crafted cpio file.(CVE-2015-8915)

  - Absolute path traversal vulnerability in bsdcpio in
    libarchive 3.1.2 and earlier allows remote attackers to
    write to arbitrary files via a full pathname in an
    archive.(CVE-2015-2304)
