3. Description:

Python is an interpreted, interactive, object-oriented programming
language, which includes modules, classes, exceptions, very high level
dynamic data types and dynamic typing. Python supports interfaces to many
system calls and libraries, as well as to various windowing systems.

The following packages have been upgraded to a later upstream version:
rh-python36-python (3.6.9). (BZ#1709344)

Security Fix(es):

* 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: Cookie domain check returns incorrect results (CVE-2018-20852)

* python: NULL pointer dereference using a specially crafted X509
certificate (CVE-2019-5010)

* python: CRLF injection via the query part of the url passed to urlopen()
(CVE-2019-9740)

* python: CRLF injection via the path part of the url passed to urlopen()
(CVE-2019-9947)

* python: email.utils.parseaddr wrongly parses email addresses
(CVE-2019-16056)

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

* python: Integer overflow in Modules/_pickle.c allows for memory
exhaustion if serializing gigabytes of data (CVE-2018-20406)

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):

* urlsplit doesn't accept a NFKD hostname with a port number (BZ#1709340)

* rh-python36 cannot unpickle datetime.date objects (BZ#1749103)
