CVE-2018-10903

A flaw was found in python-cryptography versions between =1.9.0 and 2.3. The finalizewithtag API did not enforce a minimum tag length. If a user did not validate the input length prior to passing it to finalizewithtag an attacker could craft an invalid payload with a shortened tag e.g. 1 byte suc...
