Synopsis

Description

An Incorrect Comparison vulnerability in PFE of Juniper Networks Junos OS allows an adjacent unauthenticated attacker to cause a Denial of Service (DoS). On QFX5000 Series, and EX4600 and EX4650 platforms, the fxpc process will crash followed by the FPC reboot upon receipt of a specific hostbound packet. Continued receipt of these specific packets will create a sustained Denial of Service (DoS) condition.
