To reduce duplication of effort, we have pre-built StackGuard-protected SSH
binaries and packaged them as RPMs (thanks go to Ryan Finnin Day). The
RPM's are available from our web server here:
* http://www.cse.ogi.edu/DISC/projects/immunix/StackGuard/RPMS/ssh-1.2.26-1usSG.i386.rpm
* http://www.cse.ogi.edu/DISC/projects/immunix/StackGuard/RPMS/ssh-1.2.26-1usSG.src.rpm
* http://www.cse.ogi.edu/DISC/projects/immunix/StackGuard/RPMS/ssh-clients-1.2.26-1usSG.i386.rpm
* http://www.cse.ogi.edu/DISC/projects/immunix/StackGuard/RPMS/ssh-extras-1.2.26-1usSG.i386.rpm
* http://www.cse.ogi.edu/DISC/projects/immunix/StackGuard/RPMS/ssh-server-1.2.26-1usSG.i386.rpm
I can not actually warrent that these binaries resist the alleged SSH
attack, because I've never seen the attack. If anyone thinks they actually
have an exploit for SSH, please either try it against these packages, or
send me the exploit and I'll test it.
Caveat: I'm not supposed to export these powerful weapons :-( If you're
outside the US, please don't take them from my server. If you do, it's on
your own recognicance.
If someone outside the US could please use the freely exportable StackGuard
compiler (
http://www.cse.ogi.edu/DISC/projects/immunix/StackGuard/compiler.html ) to
re-build the international version of SSH and serve that from outside the
US, I'd appreciate it.
Thanks,
Crispin
