A quick note.

Checking the source code from ssh.com, it appears that ssh-1.2.33
comes with included zlib-1.0.4, and ssh-3.1.0 comes with included
zlib-1.1.3 .

Possibly both are vulnerable.

With OpenSSH, you supply a separately installed zlib.  Presumably
versions compiled before today, including those built to handle
the channel.c problem may be vulnerable to the zlib problem.

It would be a sensible idea for people who compiled OpenSSH-3.1p1
last week to install the new zlib and rebuild OpenSSH.
