[Security] Bump urllib3 from 1.25.3 to 1.25.9 in /api

[dependabot-preview]

Bumps urllib3 from 1.25.3 to 1.25.9. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

CRLF injection urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this is similar to CVE-2020-26116.

Affected versions: < 1.25.9

Sourced from The GitHub Security Advisory Database.

Uncontrolled Resource Consumption in urllib3 The _encode_invalid_chars function in util/url.py in the urllib3 library 1.25.2 through 1.25.7 for Python allows a denial of service (CPU consumption) because of an inefficient algorithm. The percent_encodings array contains all matches of percent encodings. It is not deduplicated. For a URL of length N, the size of percent_encodings may be up to O(N). The next step (normalize existing percent-encoded bytes) also takes up to O(N) for each step, so the total time is O(N^2). If percent_encodings were deduplicated, the time to compute _encode_invalid_chars would be O(kN), where k is at most 484 ((10+6*2)^2).

Affected versions: >= 1.25.2, <= 1.25.7

Changelog

Sourced from urllib3's changelog.

1.25.9 (2020-04-16)

• Added InvalidProxyConfigurationWarning which is raised when erroneously specifying an HTTPS proxy URL. urllib3 doesn't currently support connecting to HTTPS proxies but will soon be able to and we would like users to migrate properly without much breakage.

  See this GitHub issue for more information on how to fix your proxy config. (Pull #1851)

• Drain connection after PoolManager redirect (Pull #1817)

• Ensure load_verify_locations raises SSLError for all backends (Pull #1812)

• Rename VerifiedHTTPSConnection to HTTPSConnection (Pull #1805)

• Allow the CA certificate data to be passed as a string (Pull #1804)

• Raise ValueError if method contains control characters (Pull #1800)

• Add __repr__ to Timeout (Pull #1795)

1.25.8 (2020-01-20)

• Drop support for EOL Python 3.4 (Pull #1774)
• Optimize _encode_invalid_chars (Pull #1787)

1.25.7 (2019-11-11)

• Preserve chunked parameter on retries (Pull #1715, Pull #1734)
• Allow unset SERVER_SOFTWARE in App Engine (Pull #1704, Issue #1470)
• Fix issue where URL fragment was sent within the request target. (Pull #1732)
• Fix issue where an empty query section in a URL would fail to parse. (Pull #1732)
• Remove TLS 1.3 support in SecureTransport due to Apple removing support (Pull #1703)

1.25.6 (2019-09-24)

• Fix issue where tilde (~) characters were incorrectly percent-encoded in the path. (Pull #1692)

1.25.5 (2019-09-19)

• Add mitigation for BPO-37428 affecting Python <3.7.4 and OpenSSL 1.1.1+ which caused certificate verification to be enabled when using cert_reqs=CERT_NONE. (Issue #1682)

1.25.4 (2019-09-19)

• Propagate Retry-After header settings to subsequent retries. (Pull #1607)
• Fix edge case where Retry-After header was still respected even when explicitly opted out of. (Pull #1607)
• Remove dependency on rfc3986 for URL parsing.
• Fix issue where URLs containing invalid characters within Url.auth would raise an exception instead of percent-encoding those characters.
• Add support for HTTPResponse.auto_close = False which makes HTTP responses work well with BufferedReaders and other io module features. (Pull #1652)
• Percent-encode invalid characters in URL for HTTPConnectionPool.request() (Pull #1673)
