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

  - Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is
    affected by: Improper Handling of Unicode Encoding
    (with an incorrect netloc) during NFKC normalization.
    The impact is: Information disclosure (credentials,
    cookies, etc. that are cached against a given
    hostname). The components are: urllib.parse.urlsplit,
    urllib.parse.urlparse. The attack vector is: A
    specially crafted URL could be incorrectly parsed to
    locate cookies or authentication data and send that
    information to a different host than when parsed
    correctly. (CVE-2019-9636)

  - A flaw was found in the way the DES/3DES cipher was
    used as part of the TLS/SSL protocol. A
    man-in-the-middle attacker could use this flaw to
    recover some plaintext data by capturing large amounts
    of encrypted traffic between TLS/SSL server and client
    if the communication used a DES/3DES based ciphersuite.
    (CVE-2016-2183)

  - python before versions 2.7.15, 3.4.9, 3.5.6 and 3.7.0
    is vulnerable to catastrophic backtracking in the
    difflib.IS_LINE_JUNK method. An attacker could use this
    flaw to cause denial of service. (CVE-2018-1061)

  - python before versions 2.7.15, 3.4.9, 3.5.6 and 3.7.0
    is vulnerable to catastrophic backtracking in pop3lib's
    apop() method. An attacker could use this flaw to cause
    denial of service. (CVE-2018-1060)
