OpenSSH team,

The document:  http://www.openssh.com/txt/release-7.6
   - --------

    * sftp-server(8): in read-only mode, sftp-server was incorrectly
      permitting creation of zero-length files. Reported by Michal

But when I look here:  https://www.openssh.com/security.html
I don't see this item listed.  At what version was this security problem
introduced?  Or is this applicable to all versions older than 7.6?

Thanks -
