Improper Validation of Integrity Check Value

Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value in the processPacket method of KCCMBlockCipher, which invokes processAAD only when associated data is present, so with no AAD the G1 block nonce, length, flag is never mixed into the MAC and...
