netscape security hole

[David Teague <dbt@tinuviel.cs.wcu.edu>]

On NPR's Morning Edition they described a security hole in Netscape
versions 4.73 and earlier that allows 'infection' by access to
'nasty' web sites. It is said to put your hard drive at risk some
way.

I assume this is a Windows problem, BUT does anybody know what this
hole is and whether Linux is susceptible? (Probably only the user's
files would be at risk at worst.)
