medium Nessus Plugin ID 86606
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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 potentially affected by a denial of service vulnerability due to improper handling of uBFD packets that are received directly by chassis that have the 'Trio Chipset' (Trinity) MPC. A remote attacker can exploit this issue, via maliciously crafted uBFD packets, to crash the MPC line card.

Solution

Apply the relevant Junos software release referenced in Juniper advisory JSA10701.
