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. -NWR
