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.
