In Point to MultiPoint (P2MP) scenarios within established sessions between network or adjacent neighbors the improper use of a source to destination copy write operation combined with a Stack-based Buffer Overflow on certain specific packets processed by the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved sent by a remote unauthenticated network attacker causes the RPD to crash causing a Denial of Service (DoS). Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS 19.2 versions before 19.2R3-S2; 19.3 versions before 19.3R2-S6, 19.3R3-S2; 19.4 versions before 19.4R1-S4, 19.4R2-S4, 19.4R3-S3; 20.1 versions before 20.1R2-S2, 20.1R3; 20.2 versions before 20.2R2-S3, 20.2R3; 20.3 versions before 20.3R2.
