Description

A Reachable Assertion vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows to send specific genuine PIM packets to the device resulting in rpd to crash causing a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Note: This issue is not noticed when all the devices in the network are Juniper devices. This issue affects Juniper Networks: Junos OS: * All versions prior to 20.4R3-S7; * 21.2 versions prior to 21.2R3-S5; * 21.3 versions prior to 21.3R3-S4; * 21.4 versions prior to 21.4R3-S4; * 22.1 versions prior to 22.1R3-S4; * 22.2 versions prior to 22.2R3; * 22.3 versions prior to 22.3R3; * 22.4 versions prior to 22.4R3. Junos OS Evolved: * All versions prior to 22.3R3-EVO; * 22.4-EVO versions prior to 22.4R3-EVO; * 23.2-EVO versions prior to 23.2R1-EVO.
