Fix your syslog configuration.  CVS syslogs actual passwords using the
"authpriv" facility (if your syslog doesn't support that facility, CVS
doesn't log the actual passwords).  The authpriv facility is defined as
authorization messages (like login failures) containing sensitive
information, so they should be logged to a file readable only by root
(or other trusted individuals); they should *NOT* be logged to the
normal syslog file.  You need to add a line something like:

        authpriv.*      /var/log/secure

near the top of your /etc/syslog.conf (where /var/log/secure has
appropriate permissions).  Heaven only know what other kinds of
sensitive information you're publishing in your syslog.
