The reader in this package is a default bufio.Reader wrapping a net.Conn. It will read from the connection until it finds a newline. Since no limits are implemented in the code, a deliberately malformed V1 header could be used to exhaust memory in a server process using this code - and create a DoS. This can be exploited by sending a stream starting with PROXY and continuing to send data (which does not contain a newline) until the target stops acknowledging. The risk here is small, because only trusted sources should be allowed to send proxy protocol headers.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/24564"}, {"timestamp": "2021-03-19T22:06:33Z", "date_only": false, "value": "2021-03-19T22:06:33.000Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / snyk", "record": "cve-2021-23351", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2021-03-23T00:00:00Z", "date_only": true, "value": "2021-03-23", "kind": "other", "label": "Date", "source": "gsd \u00b7 GSD-2021-23351", "record": "GSD-2021-23351", "field": "namespaces.gitlab.com.advisories.0.date"}, {"timestamp": "2021-03-23T18:23:00Z", "date_only": false, "value": "2021-03-23T18:23Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-23351", "record": "GSD-2021-23351", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2021-05-18T21:07:43Z", "date_only": false, "value": "2021-05-18T21:07:43Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-FQH4-RH59-XHVF", "record": "GHSA-FQH4-RH59-XHVF", "field": "published"}, {"timestamp": "2023-09-14T19:22:34Z", "date_only": false, "value": "2023-09-14T19:22:34Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-FQH4-RH59-XHVF", "record": "GHSA-FQH4-RH59-XHVF", "field": "modified"}, {"timestamp": "2023-12-13T01:23:29.739Z", "date_only": false, "value": "2023-12-13T01:23:29.739087Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-23351", "record": "GSD-2021-23351", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-08-03T19:05:55.668Z", "date_only": false, "value": "2024-08-03T19:05:55.668Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "cve-2021-23351", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-09-17T01:31:07.953Z", "date_only": false, "value": "2024-09-17T01:31:07.953Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "cve-2021-23351", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2025-09-08T16:46:59Z", "date_only": false, "value": "2025-09-08T16:46:59Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2021-23351", "record": "UBUNTU-CVE-2021-23351", "field": "modified"}, {"timestamp": "2026-06-17T03:38:36.220Z", "date_only": false, "value": "2026-06-17T03:38:36.220", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-23351", "record": "FKIE_CVE-2021-23351", "field": "lastModified"}]}
