The AutoFill feature in Apple Safari 2.0.4 does not properly verify that all automatically populated form fields are visible to the user, which allows remote attackers to obtain sensitive information, such as usernames and passwords, via input fields of zero width, a variant of CVE-2006-6077.

The (1) Password Manager in Mozilla Firefox 2.0, and 1.5.0.8 and earlier; and the (2) Passcard Manager in Netscape 8.1.2 and possibly other versions, do not properly verify that an ACTION URL in a FORM element containing a password INPUT element matches the web site for which the user stored a password, which allows remote attackers to obtain passwords via a password INPUT element on a different web page located on the web site intended for this password.
