[原文]Netscape 4.79 and earlier for MacOS allows an attacker with access to the browser to obtain passwords from form fields by printing the document into which the password has been typed, which is printed in cleartext.
Netscape for Mac OS Form Field Password Disclosure
Local Access Required
Loss of Confidentiality
Netscape contains a flaw that may lead to an unauthorized password exposure. It is possible to gain access to plaintext passwords when a user enters a password into a password form field, and then that page is printed, which may lead to a loss of confidentiality.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
