Summarized, this exploit only works if you have in your sshd_config:
PAMAuthenticationViaKbdInt yes
UsePrivilegeSeparation no
The default values for both my unstable and stable debian boxes appear
to be:
PAMAuthenticationViaKbdInt no
UsePrivilegeSeparation yes
(according to both manpage and the files themselves)
This means that, if you haven't modified your default sshd installation,
you are safe from this vulnerability.
Kind regards,
