### 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;  *  22.2 versions earlier than 22.2R3-S3;  *  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;  *  22.1-EVO versions earlier than 22.1R3-S4;  *  22.2-EVO versions earlier than 22.2R3-S3;  *  22.3-EVO versions earlier than 22.3R3-S2;  *  22.4-EVO versions earlier than 22.4R3;  *  23.2-EVO versions earlier than 23.2R2.
