This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

According to its self-reported version number, the remote Junos device
has a denial of service vulnerability. Specially crafted IPv6 packets
that match IPv6 egress filters with a discard or reject action on the
lo0 interface can result in a memory leak. This can lead to MBUF
exhaustion, resulting in a kernel crash. A remote, unauthenticated
attacker could exploit this to crash the host.
