Receipt of a malformed BGP OPEN message may cause the routing protocol daemon (rpd) process to crash and restart. By continuously sending specially crafted BGP OPEN message packets, an attacker can repetitively crash the rpd process causing prolonged denial of service. Juniper SIRT is not aware of any malicious exploitation of this vulnerability, however, this issue has been seen in a production network due to the BGP implementation in different vendor's device. No other Juniper Networks products or platforms are affected by this issue. This issue has been assigned CVE-2017-2314 .
