Este problema se observa en las plataformas Junos y Junos Evolved donde PIM est\u00e1 configurado junto con MoFRR. MoFRR intenta seleccionar la ruta activa, pero debido a un problema de sincronizaci\u00f3n interna, rpd no puede seleccionar el siguiente salto de reenv\u00edo hacia la fuente, lo que provoca un fallo de rpd. Este problema afecta a: Junos OS: * Todas las versiones anteriores a 20.4R3-S10, * desde 21.2 anterior a 21.2R3-S7, * desde 21.4 anterior a 21.4R3-S6, * desde 22.1 anterior a 22.1R3-S5, * desde 22.2 anterior a 22.2R3- S3, * de 22.3 antes de 22.3R3, * de 22.4 antes de 22.4R2; Junos OS Evolved: *Todas las versiones anteriores a 20.4R3-S10 -EVO, *desde 21.2-EVO anteriores a 21.2R3-S7 -EVO, *desde 21.4-EVO anteriores a 21.4R3-S6 -EVO, *desde 22.1-EVO anteriores a 22.1R3- S5 -EVO, * desde 22.2-EVO antes de 22.2R3-S3-EVO, * desde 22.3-EVO antes de 22.3R3-EVO, * desde 22.4-EVO antes de 22.4R2-EVO.\"}],\"metrics\":{\"cvssMetricV40\":[{\"source\":\"sirt@juniper.net\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"4.0\",\"vectorString\":\"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:A/V:X/RE:X/U:X\",\"attackVector\":\"ADJACENT\",\"attackComplexity\":\"LOW\",\"attackRequirements\":\"NONE\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"vulnerableSystemConfidentiality\":\"NONE\",\"vulnerableSystemIntegrity\":\"NONE\",\"vulnerableSystemAvailability\":\"HIGH\",\"subsequentSystemConfidentiality\":\"NONE\",\"subsequentSystemIntegrity\":\"NONE\",\"subsequentSystemAvailability\":\"LOW\",\"exploitMaturity\":\"NOT_DEFINED\",\"confidentialityRequirements\":\"NOT_DEFINED\",\"integrityRequirements\":\"NOT_DEFINED\",\"availabilityRequirements\":\"NOT_DEFINED\",\"modifiedAttackVector\":\"NOT_DEFINED\",\"modifiedAttackComplexity\":\"NOT_DEFINED\",\"modifiedAttackRequirements\":\"NOT_DEFINED\",\"modifiedPrivilegesRequired\":\"NOT_DEFINED\",\"modifiedUserInteraction\":\"NOT_DEFINED\",\"modifiedVulnerableSystemConfidentiality\":\"NOT_DEFINED\",\"modifiedVulnerableSystemIntegrity\":\"NOT_DEFINED\",\"modifiedVulnerableSystemAvailability\":\"NOT_DEFINED\",\"modifiedSubsequentSystemConfidentiality\":\"NOT_DEFINED\",\"modifiedSubsequentSystemIntegrity\":\"NOT_DEFINED\",\"modifiedSubsequentSystemAvailability\":\"NOT_DEFINED\",\"safety\":\"NOT_DEFINED\",\"automatable\":\"NOT_DEFINED\",\"recovery\":\"AUTOMATIC\",\"valueDensity\":\"NOT_DEFINED\",\"vulnerabilityResponseEffort\":\"NOT_DEFINED\",\"providerUrgency\":\"NOT_DEFINED\",\"baseScore\":7.1,\"baseSeverity\":\"HIGH\"}}],\"cvssMetricV31\":[{\"source\":\"sirt@juniper.net\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H\",\"attackVector\":\"ADJACENT_NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\",\"baseScore\":6.5,\"baseSeverity\":\"MEDIUM\"},\"exploitabilityScore\":2.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"sirt@juniper.net\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-252\"}]}],\"references\":[{\"url\":\"https://supportportal.juniper.net/JSA83018\",\"source\":\"sirt@juniper.net\"}]}}"
