The following packages have been upgraded to a later upstream version:
rh-python38-python (3.8.6). (BZ#1885289)

Security Fix(es):

* python-psutil: double free because of refcount mishandling
(CVE-2019-18874)

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

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

* python: CRLF injection via HTTP request method in httplib/http.client
(CVE-2020-26116)

* python-urllib3: CRLF injection via HTTP request method (CVE-2020-26137)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
