[Security] Bump werkzeug from 0.14.1 to 0.15.3

[dependabot-preview]

Bumps werkzeug from 0.14.1 to 0.15.3. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

High severity vulnerability that affects werkzeug Pallets Werkzeug before 0.15.3, when used with Docker, has insufficient debugger PIN randomness because Docker containers share the same machine id.

Affected versions: < 0.15.3

Version 0.15.3

Released 2019-05-14

• Properly handle multi-line header folding in development server in Python 2.7. (1080)
• Restore the response argument to ~exceptions.Unauthorized. (1527)
• ~exceptions.Unauthorized doesn't add the WWW-Authenticate header if www_authenticate is not given. (1516)
• The default URL converter correctly encodes bytes to string rather than representing them with b''. (1502)
• Fix the filename format string in ~middleware.profiler.ProfilerMiddleware to correctly handle float values. (1511)
• Update ~middleware.lint.LintMiddleware to work on Python 3. (1510)
• The debugger detects cycles in chained exceptions and does not time out in that case. (1536)
• When running the development server in Docker, the debugger security pin is now unique per container.

Version 0.15.2

Released 2019-04-02

• Rule code generation uses a filename that coverage will ignore. The previous value, "generated", was causing coverage to fail. (1487)
• The test client removes the cookie header if there are no persisted cookies. This fixes an issue introduced in 0.15.0 where the cookies from the original request were used for redirects, causing functions such as logout to fail. (1491)
• The test client copies the environ before passing it to the app, to prevent in-place modifications from affecting redirect requests. (1498)
• The "werkzeug" logger only adds a handler if there is no handler configured for its level in the logging chain. This avoids double logging if other code configures logging first. (1492)

Version 0.15.1

Released 2019-03-21

• ~exceptions.Unauthorized takes description as the first argument, restoring previous behavior. The new www_authenticate argument is listed second. (1483)

Version 0.15.0

Released 2019-03-19

• Building URLs is ~7x faster. Each ~routing.Rule compiles an optimized function for building itself. (1281)
• MapAdapter.build() <routing.MapAdapter.build> can be passed a ~datastructures.MultiDict to represent multiple values for a key. It already did this when passing a dict with a list value. (724)
• path_info defaults to '/' for Map.bind() <routing.Map.bind>. (740, 768, 1316)
• Change RequestRedirect code from 301 to 308, preserving the verb and request body (form data) during redirect. (1342)
• int and float converters in URL rules will handle negative values if passed the signed=True parameter. For example, /jump/<int(signed=True):count>. (1355)
• Location autocorrection in Response.get_wsgi_headers() <wrappers.BaseResponse.get_wsgi_headers> is relative to the current path rather than the root path. (693, 718, 1315)
• 412 responses once again include entity headers and an error message in the body. They were originally omitted when implementing If-Match (1233), but the spec doesn't seem to disallow it. (1231, 1255)
• The Content-Length header is removed for 1xx and 204 responses. This fixes a previous change where no body would be sent, but the header would still be present. The new behavior matches RFC 7230. (1294)
• ~exceptions.Unauthorized takes a www_authenticate parameter to set the WWW-Authenticate header for the response, which is technically required for a valid 401 response. (772, 795)
• Add support for status code 424 ~exceptions.FailedDependency. (1358)
• http.parse_cookie ignores empty segments rather than producing a cookie with no key or value. (1245, 1301)
• ~http.parse_authorization_header (and ~datastructures.Authorization, ~wrappers.Request.authorization) treats the authorization header as UTF-8. On Python 2, basic auth username and password are unicode. (1325)
• ~http.parse_options_header understands 2231 parameter continuations. (1417)
