Description Need Real Name 2000-10-18 00:31:05 UTC
After upgrading default openssh on RH7.0
using openssh-clients-2.2.0p1-5.i386.rpm,
I noticed /usr/bin/ssh has protection mode as
"-rwsr-xr-x". Is this a feature or a bug?
I don't think allow ing ssh start on privilaged port
is a good idea.

Comment 1 Daniel Roesen 2000-10-18 12:14:53 UTC
I agree that the ssh client should NOT be setuid-root by default.

Comment 2 Pekka Savola 2000-10-19 18:49:30 UTC
setuid bit is required for RSAAuthentication and RhostsRSAAuthentication.

Comment 3 Daniel Roesen 2000-10-19 18:55:18 UTC
Only for RhostsRSAAuthentication, not RSAAuthentication. Otherwise I must be
doing something wrong, because RSA Auth works perfectly without suid bit set on
the client. :-]

Comment 4 Pekka Savola 2000-10-20 20:49:01 UTC
Oh.  You're correct :-)

Comment 5 Nalin Dahyabhai 2000-10-24 19:22:43 UTC
All of the above.  Any kind of RHosts authentication is based on the client
connecting from a "privileged" port, and ssh needs to be setuid in order to do
this correctly.
