"According to the versions of the python3 packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - An issue was discovered in Python through 2.7.16, 3.x
    through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through
    3.7.4. The email module wrongly parses email addresses
    that contain multiple @ characters. An application that
    uses the email module and implements some kind of
    checks on the From/To headers of a message could be
    tricked into accepting an email address that should be
    denied. An attack may be the same as in CVE-2019-11340
    however, this CVE applies to Python more
    generally.(CVE-2019-16056)

  - http.cookiejar.DefaultPolicy.domain_return_ok in
    Lib/http/cookiejar.py in Python before 3.7.3 does not
    correctly validate the domain: it can be tricked into
    sending existing cookies to the wrong server. An
    attacker may abuse this flaw by using a server with a
    hostname that has another valid hostname as a suffix
    (e.g., pythonicexample.com to steal cookies for
    example.com). When a program uses
    http.cookiejar.DefaultPolicy and tries to do an HTTP
    connection to an attacker-controlled server, existing
    cookies can be leaked to the attacker. This affects 2.x
    through 2.7.16, 3.x before 3.4.10, 3.5.x before 3.5.7,
    3.6.x before 3.6.9, and 3.7.x before
    3.7.3.(CVE-2018-20852)

  - The documentation XML-RPC server in Python through
    2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has
    XSS via the server_title field. This occurs in
    Lib/DocXMLRPCServer.py in Python 2.x, and in
    Lib/xmlrpc/server.py in Python 3.x. If set_server_title
    is called with untrusted input, arbitrary JavaScript
    can be delivered to clients that visit the http URL for
    this server.(CVE-2019-16935)

  - library/glob.html in the Python 2 and 3 documentation
    before 2016 has potentially misleading information
    about whether sorting occurs, as demonstrated by
    irreproducible cancer-research results. NOTE: the
    effects of this documentation cross application
    domains, and thus it is likely that security-relevant
    code elsewhere is affected. This issue is not a Python
    implementation bug, and there are no reports that NMR
    researchers were specifically relying on
    library/glob.html. In other words, because the older
    documentation stated 'finds all the pathnames matching
    a specified pattern according to the rules used by the
    Unix shell,' one might have incorrectly inferred that
    the sorting that occurs in a Unix shell also occurred
    for glob.glob. There is a workaround in newer versions
    of Willoughby nmr-data_compilation-p2.py and
    nmr-data_compilation-p3.py, which call sort()
    directly.(CVE-2019-17514)

has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
