Due to a security issue with OpenSSH pre-3.7.0, a new package has been made. For now you can access it from
http://qnx.wox.org/packages/6.2.x/openssh-3.7.0p1-x86-public.qpr, and it will show up in the QNX Online repository in the next day or two.
Update: Seems that 12 hours after the 3.7.0p1 pacakge was up, openssh.com released 3.7.1p1. It is now packaged and in the same location http://qnx.wox.org/packages/6.2.x/
