That exploit can use any suid root program which resolves host names. (For
example ping and traceroute) So you cannot fix that glibc explot only by
unsetting SUID bit of ssh client.

Or more properly, an suid root program which resolves host names _while still
holding root privileges_.  ping from netkit and traceroute from LBNL do not
fall into this category.  fping from SATAN, however, does.
