The host is installed with OpenSSH before 7.1p2 and is prone to information disclosure vulnerability. A flaw is present in roaming_read and roaming_write functions in roaming_common.c, which when certain proxy and forward options are enabled, do not properly maintain connection file descriptors. Successful exploitation could allow remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings.
