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

  - Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and
    IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application
    is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this
    attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12;
    v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.
    (CVE-2020-14422)

  - In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP
    address string. This (in some situations) allows attackers to bypass access control that is based on IP
    addresses. (CVE-2021-29921)

  - An issue was discovered in urllib3 before 1.26.5. When provided with a URL containing many @ characters in
    the authority component, the authority regular expression exhibits catastrophic backtracking, causing a
    denial of service if a URL were passed as a parameter or redirected to via an HTTP redirect.
    (CVE-2021-33503)
