  script_tag(name:"insight", value:"The following vulnerabilities exist:

  - CVE-2016-5636: Integer overflow in the get_data function in zipimport.c in Python allows remote
  attackers to have unspecified impact via a negative data size value, which triggers a heap-based
  buffer overflow.

  - CVE-2016-5699: CRLF injection in the HTTPConnection.putheader function in urllib2 and urllib in
  Python allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in a URL.

  - CVE-2016-0772: The smtplib library in Python does not return an error when StartTLS fails,
  which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a
  network position between the client and the registry to block the StartTLS command, aka a
  'StartTLS stripping attack'.");
