Description:
Markus Wörle has reported a security issue in Mac OS X, which may expose sensitive information to malicious people.
The problem is caused due to a design error in the Mail account creation wizard, which transmits a user's credentials in plain text to test their validity, before the user is asked to choose an optional encryption (e.g. IMAP over SSL).
This may cause a user's plain text credentials to be disclosed to a third party during the account creation process even though the user chooses to use encryption.
The security issue has been reported in Mail 2.0 on Mac OS 10.4. Other versions may also be affected.
Solution:
The security issue has reportedly been fixed in Mac OS X version 10.4.3.
