In the hint on fixing the security hole in SSH, one of the possible solutions was to install OpenSSH 2.3. No detail was provided on exactly how to do this, however! I had thought this link was already posted on the site somewhere, but a quick search failed to find it ... so I'm posting it now (again?).
To install OpenSSH 2.3, head on over to stepwise.com, and follow the excellent page of instructions written by Scott Anguish which will walk you through the process.
I have not built OpenSSH 2.3 on my machine, so you're on your own to see if it actually works. I'm sure it does, but I haven't tested it myself yet.
