The rpd crash will impact all routing protocols until the process has automatically been restarted. As the operational state which makes this issue exploitable is outside the attackers control, this issue is considered difficult to exploit. Continued execution of this command will lead to a sustained DoS.\n\nThis issue affects:\nJuniper Networks Junos OS\n19.4 version 19.4R3-S5 and later versions prior to 19.4R3-S9;\n20.1 version 20.1R2 and later versions;\n20.2 versions prior to 20.2R3-S7;\n20.3 versions prior to 20.3R3-S5;\n20.4 versions prior to 20.4R3-S6;\n21.1 versions prior to 21.1R3-S4;\n21.2 versions prior to 21.2R3-S2;\n21.3 versions prior to 21.3R3-S1;\n21.4 versions prior to 21.4R3;\n22.1 versions prior to 22.1R1-S2, 22.1R2;\n22.2 versions prior to 22.2R2.\n\nJuniper Networks Junos OS Evolved\nAll versions prior to 20.4R3-S6-EVO;\n21.1-EVO version 21.1R1-EVO and later versions;\n21.2-EVO version 21.2R1-EVO and later versions;\n21.3-EVO versions prior to 21.3R3-S1-EVO;\n21.4-EVO versions prior to 21.4R3-EVO;\n22.1-EVO versions prior to 22.1R1-S2-EVO, 22.1R2-EVO;\n22.2-EVO versions prior to 22.2R2-EVO.\n", "affected": [ { "vendor": "Juniper Networks", "product": "Junos OS", "defaultStatus": "unaffected", "versions": [ { "version": "19.4R3-S4", "status": "affected", "versionType": "custom", "lessThan": "19.4*", "changes": [ { "at": "19.4R3-S9", "status": "unaffected" } ] }, { "version": "20.1R2", "status": "affected", "versionType": "custom", "lessThan": "20.1*" }, { "version": "20.2", "status": "affected", "versionType": "custom", "lessThan": "20.2R3-S7" }, { "version": "20.3", "status": "affected", "versionType": "custom", "lessThan": "20.3R3-S5" }, { "version": "20.4", "status": "affected", "versionType": "custom", "lessThan": "20.4R3-S6" }, { "version": "21.1", "status": "affected", "versionType": "custom", "lessThan": "21.1R3-S4" }, { "version": "21.2", "status": "affected", "versionType": "custom", "lessThan": "21.2R3-S2" }, { "version": "21.3", "status": "affected", "versionType": "custom", "lessThan": "21.3R3-S1" }, { "version": "21.4", "status": "affected", "versionType": "custom", "lessThan": "21.4R3" }, { "version": "22.1", "status": "affected", "versionType": "custom", "lessThan": "22.1R1-S2, 22.1R2" }, { "version": "22.2", "status": "affected", "versionType": "custom", "lessThan": "22.2R2" } ] }, { "vendor": "Juniper Networks", "product": "Junos OS Evolved", "defaultStatus": "unaffected", "versions": [ { "version": "unspecified", "status": "affected", "versionType": "custom", "lessThan": "20.4R3-S6-EVO" }, { "version": "21.1", "status": "affected", "versionType": "custom", "lessThan": "21.1*", "changes": [ { "at": "21.1R1-EVO", "status": "affected" } ] }, { "version": "21.2", "status": "affected", "versionType": "custom", "lessThan": "21.2*", "changes": [ { "at": "21.2R1-EVO", "status": "affected" } ] }, { "version": "21.3", "status": "affected", "versionType": "custom", "lessThan": "21.3R3-S1-EVO" }, { "version": "21.4", "status": "affected", "versionType": "custom", "lessThan": "21.4R3-EVO" }, { "version": "22.1", "status": "affected", "versionType": "custom", "lessThan": "22.1R1-S2-EVO, 22.1R2-EVO" }, { "version": "22.2", "status": "affected", "versionType": "custom", "lessThan": "22.2R2-EVO" } ] } ] } } }
