During negotiation between a server and a client, the server may fail to give the WILL/WONT or DO/DONT response for DO and WILL commands because of improper handling of exception condition, which leads to property violations and denial of service. Specifically, a server sometimes sends no response, because a fixed buffer space is available for all responses and that space may have been exhausted.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/28270"}, {"timestamp": "2021-09-10T19:50:00Z", "date_only": false, "value": "2021-09-10T19:50Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-40523", "record": "GSD-2021-40523", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2022-05-24T19:13:01Z", "date_only": false, "value": "2022-05-24T19:13:01Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-9RQJ-H33R-QGM8", "record": "GHSA-9RQJ-H33R-QGM8", "field": "published"}, {"timestamp": "2022-05-24T19:13:01Z", "date_only": false, "value": "2022-05-24T19:13:01Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-9RQJ-H33R-QGM8", "record": "GHSA-9RQJ-H33R-QGM8", "field": "modified"}, {"timestamp": "2023-12-13T01:23:25.425Z", "date_only": false, "value": "2023-12-13T01:23:25.425149Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-40523", "record": "GSD-2021-40523", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-08-04T02:44:10.790Z", "date_only": false, "value": "2024-08-04T02:44:10.790Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2021-40523", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-08-04T02:44:10.790Z", "date_only": false, "value": "2024-08-04T02:44:10.790Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2021-40523", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T04:07:05.043Z", "date_only": false, "value": "2026-06-17T04:07:05.043", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-40523", "record": "FKIE_CVE-2021-40523", "field": "lastModified"}]}
