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 vulnerability in the NTP daemon related to the handling of the 'monlist' command. A remote attacker can exploit this by forging a request that results in a distributed denial of service.

Note that this issue only affects devices with NTP client or server enabled.
