Updated python-cryptography packages fix security vulnerabilityPublication date: 03 Nov 2018
Affected Mageia releases : 6
The python-cryptography and python-cryptography-vectors packages have been updated to version 2.3.1 and fixes the following security issue: 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).
