  Updated python and python3 packages fix security vulnerabilities:

  An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib
  in Python 3.x through 3.7.2. CRLF injection is possible if the attacker
  controls a url parameter, as demonstrated by the first argument to
  urllib.request.urlopen with \r\n followed by an HTTP header or a Redis
  command (CVE-2019-9740).

  An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib
  in Python 3.x through 3.7.2. CRLF injection is possible if the attacker
  controls a url parameter, as demonstrated by the first argument to
  urllib.request.urlopen with \r\n (specifically in the path component of a
  URL) followed by an HTTP header or a Redis command. This is similar to
  CVE-2019-9740 query string issue (CVE-2019-9947).

  urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which
  makes it easier for remote attackers to bypass protection mechanisms that
  blacklist file: URIs, as demonstrated by triggering a 
  urllib.urlopen('local_file:///etc/passwd') call (CVE-2019-9948).

  A security regression of CVE-2019-9636 was discovered in python, which
  still allows an attacker to exploit CVE-2019-9636 by abusing the user and
  password parts of a URL. When an application parses user-supplied URLs to
  store cookies, authentication credentials, or other kind of information,
  it is possible for an attacker to provide specially crafted URLs to make
  the application locate host-related information (e.g. cookies,
  authentication data) and send them to a different host than where it
  should, unlike if the URLs had been correctly parsed. The result of an
  attack may vary based on the application (CVE-2019-10160).

  It was discovered that Python incorrectly parsed certain email addresses.
  A remote attacker could possibly use this issue to trick Python
  applications into accepting email addresses that should be denied
  (CVE-2019-16056).

  It was discovered that the Python documentation XML-RPC server incorrectly
  handled certain fields. A remote attacker could use this issue to execute
  a cross-site scripting (XSS) attack (CVE-2019-16935).
