The following packages have been upgraded to a later upstream version:
python27-python (2.7.16). (BZ#1709349)

Security Fix(es):

* python-jinja2: Sandbox escape due to information disclosure via
str.format (CVE-2016-10745)

* python: DOS via regular expression backtracking in difflib.IS_LINE_JUNK
method in difflib (CVE-2018-1061)

* python: Missing salt initialization in _elementtree.c module
(CVE-2018-14647)

* python: improper neutralization of CRLF sequences in urllib module
(CVE-2019-9740)

* python: improper neutralization of CRLF sequences in urllib module
(CVE-2019-9947)

* python: DOS via regular expression catastrophic backtracking in apop()
method in pop3lib (CVE-2018-1060)

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.

Bug Fix(es):
