[Security] Bump cryptography from 2.2.2 to 2.4.2

Bumps cryptography from 2.2.2 to 2.4.2. This update includes security fixes.

Vulnerabilities fixed

*Sourced from The GitHub Security Advisory Database.* > **High severity vulnerability that affects cryptography** > A flaw was found in python-cryptography versions between >=1.9.0 and <2.3. The finalize_with_tag API did not enforce a minimum tag length. If a user did not validate the input length prior to passing it to finalize_with_tag an attacker could craft an invalid payload with a shortened tag (e.g. 1 byte) such that they would have a 1 in 256 chance of passing the MAC check. GCM tag forgeries can cause key leakage. > > Affected versions: >= 1.9.0, < 2.3

Changelog

*Sourced from [cryptography's changelog](https://github.com/pyca/cryptography/blob/master/CHANGELOG.rst).* > 2.4.2 - 2018-11-21 > ~~~~~~~~~~~~~~~~~~ > > * Updated Windows, macOS, and ``manylinux1`` wheels to be compiled with > OpenSSL 1.1.0j. > > .. _v2-4-1: > > 2.4.1 - 2018-11-11 > ~~~~~~~~~~~~~~~~~~ > > * Fixed a build breakage in our ``manylinux1`` wheels. > > .. _v2-4: > > 2.4 - 2018-11-11 > ~~~~~~~~~~~~~~~~ > > * **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL 2.4.x. > * Deprecated OpenSSL 1.0.1 support. OpenSSL 1.0.1 is no longer supported by > the OpenSSL project. At this time there is no time table for dropping > support, however we strongly encourage all users to upgrade or install > ``cryptography`` from a wheel. > * Added initial :doc:`OCSP ` support. > * Added support for :class:`~cryptography.x509.PrecertPoison`. > > .. _v2-3-1: > > 2.3.1 - 2018-08-14 > ~~~~~~~~~~~~~~~~~~ > > * Updated Windows, macOS, and ``manylinux1`` wheels to be compiled with > OpenSSL 1.1.0i. > > .. _v2-3: > > 2.3 - 2018-07-18 > ~~~~~~~~~~~~~~~~ > > * **SECURITY ISSUE:** > :meth:`~cryptography.hazmat.primitives.ciphers.AEADDecryptionContext.finalize_with_tag` > allowed tag truncation by default which can allow tag forgery in some cases. > The method now enforces the ``min_tag_length`` provided to the > :class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` constructor. > *CVE-2018-10903* > * Added support for Python 3.7. > * Added :meth:`~cryptography.fernet.Fernet.extract_timestamp` to get the > authenticated timestamp of a :doc:`Fernet ` token. > * Support for Python 2.7.x without ``hmac.compare_digest`` has been deprecated. > We will require Python 2.7.7 or higher (or 2.7.6 on Ubuntu) in the next > ...
