[Security] Bump urllib3 from 1.22 to 1.24.2

[dependabot-preview]

Bumps urllib3 from 1.22 to 1.24.2. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

High severity vulnerability that affects urllib3
The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA certificates is different from the OS store of CA certificates, which results in SSL connections succeeding in situations where a verification failure is the correct outcome. This is related to use of the ssl_context, ca_certs, or ca_certs_dir argument.

Affected versions: < 1.24.2

Sourced from The GitHub Security Advisory Database.

High severity vulnerability that affects urllib3
urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the Authorization header to be exposed to unintended hosts or transmitted in cleartext.

Affected versions: < 1.23

Changelog

Sourced from urllib3's changelog.

1.24.2 (2019-04-17)

• Don't load system certificates by default when any other ca_certs, ca_certs_dir or ssl_context parameters are specified.
• Remove Authorization header regardless of case when redirecting to cross-site. (Issue #1510)
• Add support for IPv6 addresses in subjectAltName section of certificates. (Issue #1269)

1.24.1 (2018-11-02)

• Remove quadratic behavior within GzipDecoder.decompress() (Issue #1467)
• Restored functionality of ciphers parameter for create_urllib3_context(). (Issue #1462)

1.24 (2018-10-16)

• Allow key_server_hostname to be specified when initializing a PoolManager to allow custom SNI to be overridden. (Pull #1449)
• Test against Python 3.7 on AppVeyor. (Pull #1453)
• Early-out ipv6 checks when running on App Engine. (Pull #1450)
• Change ambiguous description of backoff_factor (Pull #1436)
• Add ability to handle multiple Content-Encodings (Issue #1441 and Pull #1442)
• Skip DNS names that can't be idna-decoded when using pyOpenSSL (Issue #1405).
• Add a server_hostname parameter to HTTPSConnection which allows for overriding the SNI hostname sent in the handshake. (Pull #1397)
• Drop support for EOL Python 2.6 (Pull #1429 and Pull #1430)
• Fixed bug where responses with header Content-Type: message/* erroneously raised HeaderParsingError, resulting in a warning being logged. (Pull #1439)

• Fixed pyOpenSSL-specific ssl client authentication issue when clients attempted to auth via certificate + chain (Issue #1060)
• Add the port to the connectionpool connect print (Pull #1251)
• Don't use the uuid module to create multipart data boundaries. (Pull #1380)
