Hello,

I tried to compile the latest portable version (openssh-3.1p1)
to no avail.

I tried 2 different configuration combinations with the same
problem.

./configure --with-pam --with-tcp-wrappers --with-md5-passwords

and

./configure

Attached is my results of "make".

I'm doing this on Redhat 7.0

1. Systems affected:

	All versions of OpenSSH between 2.0 and 3.0.2 contain
	an off-by-one error in the channel code.

	OpenSSH 3.1 and later are not affected.

2. Impact:

        This bug can be exploited locally by an authenticated user
        logging into a vulnerable OpenSSH server or by a malicious
        SSH server attacking a vulnerable OpenSSH client.
	
3. Solution:

	Upgrade to OpenSSH 3.1 or apply the following patch.

4. Credits:

	This bug was discovered by Joost Pol <joost at pine.nl>
