Description

A vulnerability exists in versions of Netscape prior to 4.77 that allow a remote web server that the user is accessing to obtain information about the client using Netscape's internal 'about:' protocol. Other internal protocols can be accessed this way, such as the 'about:global' protocol which will display the browser history, or the 'about:config' protocol which will display the browser configuration. These problems are directly related to JavaScript processing embedded commands in GIF files which Netscape does not properly escape, and can be negated by disabling JavaScript in Netscape. However it is recommended that all users upgrade to version 4.77.
