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

  - 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)

  - OpenEMR version 5.0.0 contains a Cross Site Scripting
    (XSS) vulnerability in open-flash-chart.swf and
    _posteddata.php that can result in . This vulnerability
    appears to have been fixed in 5.0.0 Patch 2 or
    higher.(CVE-2018-1000020)

  - OpenEMR version 5.0.0 contains a OS Command Injection
    vulnerability in fax_dispatch.php that can result in OS
    command injection by an authenticated attacker with any
    role. This vulnerability appears to have been fixed in
    5.0.0 Patch 2 or higher.(CVE-2018-1000019)
