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

[Walter Tautz <wtautz@math.uwaterloo.ca>]

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.
