An Incomplete Cleanup vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS). An rpd crash can occur when an MPLS TE tunnel configuration change occurs on a directly connected router. This issue affects: Juniper Networks Junos OS All versions prior to 18.4R2-S7; 19.1 versions prior to 19.1R3-S2; 19.2 versions prior to 19.2R3; 19.3 versions prior to 19.3R3; 19.4 versions prior to 19.4R3; 20.1 versions prior to 20.1R2; 20.2 versions prior to 20.2R2. Juniper Networks Junos OS Evolved All versions prior to 19.2R3-EVO; 19.3 versions prior to 19.3R3-EVO; 19.4 versions prior to 19.4R3-EVO; 20.1 versions prior to 20.1R3-EVO; 20.2 versions prior to 20.2R2-EVO.
