Hi, Sorry, for repeating the mail. The earlier mail had a wrong subject. It might be misleading or not tempting enough for reading. The content is repeated below: 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 __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
