SASL Authentication Failure & Postfix

[Biswatosh]

Hi, 

Any info on  CVE-2006-1721 (titled  Cyrus SASL Remote
Digest-MD5 Denial of Service Vulnerability) ?
See:
http://www.securityfocus.com/bid/17446/info 

As I see, the current version has the problem fixed.
I am interested in knowing :

1)The Bug Id, by which can see about the Bug.

2)If Bug Id is not there, any idea, what was the exact
problem in digestmd5.c and how was it solved?

3)It looks this problem was in version 2.1.18. Which
version fixed it?


Thanks
Biswatosh
