extremely long URLs.

We won't be shipping it in FreeBSD 4.0, or until this gets addressed. It's a shame because it's such a popular and useful tool, but the risk to users is just too great. Thanks for notifying the world of these problems :)
I was trying to exploit lynx bug several times. It's true that lynx segfaults on long URLs, but exploiting it is (IMHO) impossible because lynx strips all nonprintable characters thus smugling RET address is impossible. I have never heard about ASCII only shellcode also:) I assume lynx bugs are unexploitable... P.S. You can compile lynx using StackGuard also (AFAIK only under Linux). -- Mariusz Wo³oszyn Internet Security Specialist, Internet Partners, GTS Poland
