It is supposed to hang (reading standard input) when (incorrectly)
invoked this way.  You've left out the CAfile filename.  The correct
way to verify a certificate is:

    $ trusted=ta.pem
    $ untrusted=intermediate.pem
    $ subject=server.pem
    $ openssl verify -CAfile $trusted -untrusted $untrusted $subject

where 

 * "ta.pem" contains your trust-anchor (root CA) certificates,
 * "intermediate.pem" contains any intermediate certificates needed to
    build a trust path from a root down to the server certificate,
 * "server.pem" contains the subject certificate to be verified.

Leave out the "-untrusted $untrusted" option if you're verifying
a certificate that is directly issued by a trust-anchor.

With a sufficiently recent version of OpenSSL replace "-CAfile
$trusted" with "-trusted $trusted" to make sure you're not
inadvertently using any of the default trust-anchors installed on
your system.
