In version 3.5.0024 and prior, a remotely exploitable integer underflow vulnerability in the DNS packet decompression function allows an attacker to cause a Denial of Service by triggering an abnormal program termination.The vulnerability exists in the `decomp_get_rddata` function within the `Decompress.c` file. When handling a DNS packet with an Answer RR of qtype 16 (TXT record) and any qclass, if the `rdlength` is smaller than `rdata`, the result of the line `Decompress.c:886` is a negative number `len = rdlength - total;`. This value is then passed to the `decomp_append_bytes` function without proper validation, causing the program to attempt to allocate a massive chunk of memory that is impossible to allocate. Consequently, the program exits with an error code of 64, causing a Denial of Service.One proposed fix for this vulnerability is to patch `Decompress.c:887` by breaking `if(len <= 0)`, which has been incorporated in version 3.5.0036 via commit bab062bde40b2ae8a91eecd522e84d8b993bab58.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/63625"}, {"timestamp": "2023-06-29T11:06:15.332Z", "date_only": false, "value": "2023-06-29T11:06:15.332Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / GitHub_M", "record": "CVE-2023-31137", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2023-12-13T01:20:30.205Z", "date_only": false, "value": "2023-12-13T01:20:30.205798Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2023-31137", "record": "GSD-2023-31137", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-03-07T19:56:58.690Z", "date_only": false, "value": "2024-03-07T19:56:58.690", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2023-31137", "record": "GSD-2023-31137", "field": "namespaces.nvd.nist.gov.cve.lastModified"}, {"timestamp": "2024-03-08T16:26:06.644Z", "date_only": false, "value": "2024-03-08T16:26:06.644708Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2023-31137", "field": "containers.adp.1.metrics.0.other.content.timestamp"}, {"timestamp": "2024-03-08T16:26:06.644Z", "date_only": false, "value": "2024-03-08T16:26:06.644708Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-31137", "record": "FKIE_CVE-2023-31137", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2024-08-02T14:45:25.771Z", "date_only": false, "value": "2024-08-02T14:45:25.771Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2023-31137", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-11-27T16:19:59.296Z", "date_only": false, "value": "2024-11-27T16:19:59.296Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2023-31137", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2025-02-13T16:49:46.296Z", "date_only": false, "value": "2025-02-13T16:49:46.296Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2023-31137", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2025-09-08T16:56:16Z", "date_only": false, "value": "2025-09-08T16:56:16Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2023-31137", "record": "UBUNTU-CVE-2023-31137", "field": "modified"}, {"timestamp": "2026-06-17T05:56:21.527Z", "date_only": false, "value": "2026-06-17T05:56:21.527", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2023-31137", "record": "FKIE_CVE-2023-31137", "field": "lastModified"}]}
