           Summary: sftp segfaults on an attempt to up/download a
                    nonexistent file
           Product: Portable OpenSSH
           Version: -current
          Platform: ix86
               URL: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=34019
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sftp
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: roam at ringlet.net


When the name of a non-existent file is given as the argument
to a 'get' or 'put' command, sftp(1) fails to interpret correctly
the result of the glob(3) invocation.  glob(3) does not return
an error (a non-zero exit), yet it does not return any meaningful
file names, either, so process_get() and process_put()'s attempts
to access the gl_pathv[] array fail miserably.

A trivial patch is posted in the audit-trail of the FreeBSD
problem report referenced by the URL above.
