Vulnerability Description
An Improper Handling of Length Parameter Inconsistency vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network based, unauthenticated attacker to cause an RPD crash leading to a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Upon receipt of a malformed BGP flowspec update, RPD will crash resulting in a Denial of Service.
