    * python: infinite loop in the tarfile module via crafted TAR archive (CVE-2019-20907)

    * PyYAML: arbitrary command execution through python/object/new when FullLoader is used (CVE-2020-1747)

    * python: wrong backtracking in urllib.request.AbstractBasicAuthHandler allows for a ReDoS (CVE-2020-8492)

    * python: DoS via inefficiency in IPv{4,6}Interface classes (CVE-2020-14422)
