An Out-of-Bounds Read vulnerability in

the routing protocol daemon (rpd) of

Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, logically adjacent BGP peer sending a specifically malformed BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.

This issue only affects systems configured in either of two ways:

and can be exploited from a directly connected and configured BGP peer. 

This issue affects iBGP and eBGP

with

any address family

configured, and both IPv4 and IPv6 are affected by this vulnerability.
