Juniper Junos DOS (JSA69714)

medium Nessus Plugin ID 163435

Synopsis

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

Description

A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on QFX5000 Series and MX Series allows an unauthenticated adjacent attacker to cause a Denial of Service (DoS).

On QFX5K Series and MX Series, when the PFE receives a specific VxLAN packet the Layer 2 Address Learning Manager (L2ALM) process will crash leading to an FPC reboot. Continued receipt of this specific packet will create a sustained Denial of Service (DoS) condition.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the relevant Junos software release referenced in Juniper advisory JSA69714
