is openssh version (in potato) 1.2.3-9.4 vulnerable?

[Walter Tautz]

the following reports:

http://www.cert.org/incident_notes/IN-2001-12.html
            http://www.cert.org/advisories/CA-2001-35.html

which apparently refers to ssh1 crc-32 compensation attack detector
and some other problems?

                Judging from the page there openssh is fixed only in version 
2.3.0 and
                later? Or has the one in potato been patched so that none of 
these
                vulnerabilities.
