The SMTP server in Postfix before 2.5.13, 2.6.x before 2.6.10, 2.7.x before
2.7.4, and 2.8.x before 2.8.3, when certain Cyrus SASL authentication
methods are enabled, does not create a new server handle after client
authentication fails, which allows remote attackers to cause a denial of
service (heap memory corruption and daemon crash) or possibly execute
arbitrary code via an invalid AUTH command with one method followed by an
AUTH command with a different method.
