Summary
======

Description

CVE-2011-1720:

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   yrus   SASL
authentication methods are enabled, does not create a new server handle
after client authentication fails, which  allows  remote  attackers  to

method followed by an AUTH command with a different method.



Affected packages:
