An Improper Check for Unusual or Exceptional Conditions vulnerability in Routing Protocol Daemon (RPD) of Juniper Networ

An Improper Check for Unusual or Exceptional Conditions vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause rpd to crash, leading to Denial of Service (DoS). On all Junos OS and Junos OS Evolved platforms, when NETCONF and gRPC are enabled, and a specific query is executed via Dynamic Rendering (DREND), rpd will crash and restart. Continuous execution of this specific query will cause a sustained Denial of Service (DoS) condition.

This issue affects: Juniper Networks Junos OS 22.2 versions earlier than 22.2R2-S2, 22.2R3; 22.3 versions earlier than 22.3R2, 22.3R3. Juniper Networks Junos OS Evolved 22.2 versions earlier than 22.2R2-S2-EVO, 22.2R3-EVO; 22.3 versions earlier than 22.3R2-EVO, 22.3R3-EVO. This issue does not affect Juniper Networks: Junos OS versions earlier than 22.2R1; Junos OS Evolved versions earlier than 22.2R1-EVO.
