Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue can only be triggered by sending a specific malformed packet to the device. Transit traffic does not trigger this issue. An indication of this issue occurring can be seen through the following log messages: fpc0 expr_hostbound_packet_handler: Receive pe 73? fpc0 Cmerror Op Set: PE Chip: PE0[0]: PGQ:misc_intr: 0x00000020: Enqueue of a packet with out-of-range VOQ in 192K-VOQ mode (URI: /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_PGQ_MISC_INT_EVENTS_ENQ_192K_VIOL) The logs list below can also be observed when this issue occurs fpc0 Error: /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_PGQ_MISC_INT_EVENTS_ENQ_192K_VIOL (0x210107), scope: pfe, category: functional, severity: major, module: PE Chip, type: Description for PECHIP_CMERROR_PGQ_MISC_INT_EVENTS_ENQ_192K_VIOL fpc0 Performing action cmalarm for error /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_PGQ_MISC_INT_EVENTS_ENQ_192K_VIOL (0x210107) in module: PE Chip with scope: pfe category: functional level: major fpc0 Error: /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_CM_INT_REG_DCHK_PIPE (0x21011a), scope: pfe, category: functional, severity: fatal, module: PE Chip, type: Description for PECHIP_CMERROR_CM_INT_REG_DCHK_PIPE fpc0 Performing action cmalarm for error /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_CM_INT_REG_DCHK_PIPE (0x21011a) in module: PE Chip with scope: pfe category: functional level: fatal fpc0 Performing action disable-pfe for error /fpc/0/pfe/0/cm/0/PE_Chip/0/PECHIP_CMERROR_CM_INT_REG_DCHK_PIPE (0x21011a) in module: PE Chip with scope: pfe category: functional level: fatal This issue affects Juniper Networks Junos OS on QFX10002: All versions prior to 19.1R3-S10; 19.4 versions prior to 19.4R3-S11; 20.2 versions prior to 20.2R3-S7; 20.4 versions prior to 20.4R3-S6; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3-S4; 21.3 versions prior to 21.3R3-S3; 21.4 versions prior to 21.4R3-S2; 22.1 versions prior to 22.1R3-S1; 22.2 versions prior to 22.2R2-S1, 22.2R3; 22.3 versions prior to 22.3R1-S2, 22.3R2." } ], "affected": [ { "vendor": "Juniper Networks", "product": "Junos OS", "versions": [ { "version": "unspecified", "lessThan": "19.1R3-S10", "status": "affected", "versionType": "custom" }, { "version": "19.4", "status": "affected", "lessThan": "19.4R3-S11", "versionType": "custom" }, { "version": "20.2", "status": "affected", "lessThan": "20.2R3-S7", "versionType": "custom" }, { "version": "20.4", "status": "affected", "lessThan": "20.4R3-S6", "versionType": "custom" }, { "version": "21.1", "status": "affected", "lessThan": "21.1R3-S4", "versionType": "custom" }, { "version": "21.2", "status": "affected", "lessThan": "21.2R3-S4", "versionType": "custom" }, { "version": "21.3", "status": "affected", "lessThan": "21.3R3-S3", "versionType": "custom" }, { "version": "21.4", "status": "affected", "lessThan": "21.4R3-S2", "versionType": "custom" }, { "version": "22.1", "status": "affected", "lessThan": "22.1R3-S1", "versionType": "custom" }, { "version": "22.2", "status": "affected", "lessThan": "22.2R2-S1, 22.2R3", "versionType": "custom" }, { "version": "22.3", "status": "affected", "lessThan": "22.3R1-S2, 22.3R2", "versionType": "custom" } ], "platforms": [ "QFX10002" ] } ], "references": [ { "url": "https://supportportal.juniper.net/JSA70584" } ], "metrics": [ { "cvssV3_1": { "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" } } ], "problemTypes": [ { "descriptions": [ { "type": "CWE", "lang": "en", "description": "CWE-703 Improper Check or Handling of Exceptional Conditions", "cweId": "CWE-703" } ] } ], "x_generator": { "engine": "Vulnogram 0.0.9" }, "source": { "advisory": "JSA70584", "defect": [ "1686793" ], "discovery": "USER" }, "workarounds": [ { "lang": "en", "value": "There are no available workarounds for this issue." } ], "exploits": [ { "lang": "en", "value": "Juniper SIRT is not aware of any malicious exploitation of this vulnerability." } ], "solutions": [ { "lang": "en", "value": "The following software releases have been updated to resolve this specific issue: 19.4R3-S11, 20.2R3-S7, 20.4R3-S6, 21.1R3-S4, 21.2R3-S4, 21.3R3-S3, 21.4R3-S2, 22.1R3-S1, 22.2R2-S1, 22.2R3, 22.3R1-S2, 22.3R2, 22.4R1, and all subsequent releases.\n" } ] }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T13:51:38.983Z" }, "title": "CVE Program Container", "references": [ { "url": "https://supportportal.juniper.net/JSA70584", "tags": [ "x_transferred" ] } ] } ] } }
