I've found a Netscape bug which I suspect is a buffer overflow and may have the potential for serious damage. If it is an overflow bug, then it may be possible to infect every computer which accesses a web page with Netscape. To see the bug, create an html file containing the following:
Oh brother, this is unbelievable ! I'm using Netscape 1.1N under SunOS 4.1.2. It turns out that the same (or a similar) flaw resides in the Open Location input routine -- perhaps this merely coincides with the code called when a URL is clicked. Anyway, pasting a URL with an overlong domain name a la Ray's example causes two things: (1) Part of the Open Location window widget, below the entry box, gets overwritten onscreen with a portion of the entered URL. (2) Netscape crashes with a segmentation fault (no core dump that I can see). -Futplex <futplex@pseudonym.com>
