#15960: Segfault in HSPOST control command
---------------------+------------------------------------
 Reporter:  donncha  |          Owner:
     Type:  defect   |         Status:  new
 Priority:  major    |      Milestone:  Tor: 0.2.7.x-final

---------------------+------------------------------------
 A segfault occurs in the HSPOST command if `node->rs->is_hs_dir` is
 checked but the router_status entry for the node does not exist. I have a
 fix for this issue on my Github -
 https://github.com/DonnchaC/tor/commit/27f006bcad4a1a27339130ffb09637f4baaf7dbe

         if (!node->rs->is_hs_dir) {
           connection_printf_to_buf(conn, "552 Server \"%s\" is not a
 HSDir"
                                          "\r\n", server);
           goto done;
         }
