TITLE:
Mac OS X Mail Account Wizard Exposure of User Credentials

SECUNIA ADVISORY ID:
SA15301

VERIFY ADVISORY:
http://secunia.com/advisories/15301/

CRITICAL:
Not critical

IMPACT:
Exposure of sensitive information

WHERE:
>From remote

OPERATING SYSTEM:
Apple Macintosh OS X
http://secunia.com/product/96/

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:
Enter a invalid password before setting encryption options.
