Synopsis :

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

Description :

According to its self-reported version number, the remote Juniper
Junos device is affected by a denial of service vulnerability in the
Juniper PPP daemon (jpppd). A remote attacker can exploit this issue
by sending a specially crafted PAP Authenticate-Request after
successful negotiation of the PPPoE Discovery and LCP phase, resulting
in the PPP daemon crashing.

Note that this issue only affects MX series routers deployed as a
broadband edge (BBE) router.
