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

  - archive_read_format_rar_read_data in
    archive_read_support_format_rar.c in libarchive before
    3.4.0 has a use-after-free in a certain ARCHIVE_FAILED
    situation, related to
    Ppmd7_DecodeSymbol.(CVE-2019-18408)

  - 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)

  - 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)

  - 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)

  - An error in the lha_read_file_header_1() function
    (archive_read_support_format_lha.c) in libarchive 3.2.2
    allows remote attackers to trigger an out-of-bounds
    read memory access and subsequently cause a crash via a
    specially crafted archive.(CVE-2017-5601)

  - read_header in archive_read_support_format_rar.c in
    libarchive 3.3.2 suffers from an off-by-one error for
    UTF-16 names in RAR archives, leading to an
    out-of-bounds read in
    archive_read_format_rar_read_header.(CVE-2017-14502)

  - 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)

  - 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_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_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)

  - libarchive version commit
    416694915449219d505531b1096384f3237dd6cc onwards
    (release v3.1.0 onwards) contains a CWE-416: Use After
    Free vulnerability in RAR decoder -
    libarchive/archive_read_support_format_rar.c that can
    result in Crash/DoS - it is unknown if RCE is possible.
    This attack appear to be exploitable via the victim
    must open a specially crafted RAR
    archive.(CVE-2018-1000878)

  - libarchive version commit
    416694915449219d505531b1096384f3237dd6cc onwards
    (release v3.1.0 onwards) contains a CWE-415: Double
    Free vulnerability in RAR decoder -
    libarchive/archive_read_support_format_rar.c,
    parse_codes(), realloc(rar->lzss.window, new_size) with
    new_size = 0 that can result in Crash/DoS. This attack
    appear to be exploitable via the victim must open a
    specially crafted RAR archive.(CVE-2018-1000877)

  - 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)
