NVD Description

Note: Versions mentioned in the description apply only to the upstream postfix-perl-scripts package and not the postfix-perl-scripts package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

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.
