In a Point-to-Multipoint (P2MP) Label Switched Path (LSP) scenario, an uncontrolled resource consumption vulnerability in the Routing Protocol Daemon (RPD) in Juniper Networks Junos OS allows a specific SNMP request to trigger an infinite loop causing a high CPU usage Denial of Service (DoS) condition. This issue affects both SNMP over IPv4 and IPv6. This issue affects: Juniper Networks Junos OS: 12.3X48 versions prior to 12.3X48-D90; 15.1 versions prior to 15.1R7-S6; 15.1X49 versions prior to 15.1X49-D200; 15.1X53 versions prior to 15.1X53-D238, 15.1X53-D592; 16.1 versions prior to 16.1R7-S5; 16.2 versions prior to 16.2R2-S11; 17.1 versions prior to 17.1R3-S1; 17.2 versions prior to 17.2R3-S2; 17.3 versions prior to 17.3R3-S7; 17.4 versions prior to 17.4R2-S4, 17.4R3; 18.1 versions prior to 18.1R3-S5; 18.2 versions prior to 18.2R3; 18.2X75 versions prior to 18.2X75-D50; 18.3 versions prior to 18.3R2; 18.4 versions prior to 18.4R2; 19.1 versions prior to 19.1R2.
