SCA: security update for cryptography (GHSA-fcf9-3qw3-gxmj)

high Tenable Cloud Security Plugin ID 422447

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2018-10903)
