+Subject: [PATCH] Prevent template validate from scanning ports
+
+The template validation method in the heat API allows to specify the
+template to validate using a URL with the 'template_url' parameter.
+
+By entering invalid http URLs, like 'http://localhost:22' it is
+possible to scan ports by evaluating the error message of the request.
+
+For example, the request
+
+curl -H "Content-Type: application/json" -H "X-Auth-Token: <TOKEN>" \
+-X POST -d '{"template_url": "http://localhost:22"}' \
+http://127.0.0.1:8004/v1/<TENANT_ID>/validate
+
+causes the following error message to be returned to the user:
+
+"Could not retrieve template: Failed to retrieve template:
+('Connection aborted.',
+BadStatusLine('SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.1\\r\\n',))"
+
+This could be misused by tenants to gain knowledge about the internal
+network the heat API runs in.
+
+To prevent this information leak, this patch alters the error message
+to not include such details when the url scheme is not 'file'.
