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 due to improper TCP packet reassembly. An unauthenticated, remote attacker can exploit this, via a specially crafted sequence of fragmented packets, to consume all available buffers, resulting in a denial of service condition.
