The remote device is missing a vendor-supplied security patch.


According to its self-reported version number, the remote Juniper Junos device is affected by a denial of service vulnerability in the jdhcpd daemon due to failure to handle exceptional conditions. An unauthenticated, remote attacker can exploit this, via sending specific IPv6 DHCP packets to the jdhcpd daemon to cause a denial of service condition to clients requesting and not receiving IP addresses.
