According to its self-reported version number, the remote Juniper Junos device is affected by a remote code execution vulnerability in the BFD daemon (bfdd). A remote attacker, using a specially crafted BFD packet, can exploit this to cause a denial of service or execute arbitrary code.
Note that this issue only affects devices with the BFD daemon running.
