sshd dieing? after applying FreeBSD-SA-03:12.openssh

[Devon Sean McCullough]

On Wed, 17 Sep 2003 00:02:33 +0100 Steven Hartland asked this question
but no answer was posted.  The trouble is likely no client reverse DNS
either because it is missing or slow.  Adding the client to /etc/hosts
on the server seems at first to do nothing but after a minute or so it
stops hanging and asks for a password.  Could be a coincidence though.

To recap:
$ ssh -v me at my-freebsd-5.1-RELEASE-box
OpenSSH_3.4p1+CAN-2004-0175, SSH protocols 1.5/2.0, OpenSSL 0x0090609f

<---Here the client hangs until timeout.

To debug: kill the server process and run # sshd -ddde
