Vulnerability Title
Junos OS and Junos OS Evolved: Malformed BGP UPDATE causes RPD crash
Source: CVE Program / CVE List V5
Vulnerability Description
An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a network based, unauthenticated attacker to cause the RPD process to crash leading to a Denial of Service (DoS).
When a malformed BGP UPDATE packet is received over an established BGP session, RPD crashes and restarts.
Continuous receipt of the malformed BGP UPDATE messages will create a sustained Denial of Service (DoS) condition for impacted devices.
This issue affects eBGP and iBGP, in both IPv4 and IPv6 implementations. This issue requires a remote attacker to have at least one established BGP session.
This issue affects:
Juniper Networks Junos OS:
* All versions earlier than 20.4R3-S9;
* 21.2 versions earlier than 21.2R3-S7;
* 21.3 versions earlier than 21.3R3-S5;
* 21.4 versions earlier than 21.4R3-S6;
* 22.1 versions earlier than 22.1R3-S4;

* 22.3 versions earlier than 22.3R3-S2;
* 22.4 versions earlier than 22.4R3;
* 23.2 versions earlier than 23.2R2.
Juniper Networks Junos OS Evolved:
* All versions earlier than 21.2R3-S7;
* 21.3-EVO versions earlier than 21.3R3-S5;
* 21.4-EVO versions earlier than 21.4R3-S8;
