This does not affect organizations that only install the Varnish Cache product; however, it is common to install both Varnish Cache and varnish-modules. Specifically, an assertion failure or NULL pointer dereference can be triggered in Varnish Cache through the varnish-modules header.append() and header.copy() functions. For some Varnish Configuration Language (VCL) files, this gives remote clients an opportunity to cause a Varnish Cache restart. A restart reduces overall availability and performance due to an increased number of cache misses, and may cause higher load on backend servers.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/24950"}, {"timestamp": "2021-03-22T03:06:12Z", "date_only": false, "value": "2021-03-22T03:06:12.000Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / mitre", "record": "cve-2021-28543", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2021-03-26T20:48:00Z", "date_only": false, "value": "2021-03-26T20:48Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-28543", "record": "GSD-2021-28543", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2022-05-24T22:01:29Z", "date_only": false, "value": "2022-05-24T22:01:29Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-JPM5-7XH4-QGJV", "record": "GHSA-JPM5-7XH4-QGJV", "field": "published"}, {"timestamp": "2022-06-29T00:00:49Z", "date_only": false, "value": "2022-06-29T00:00:49Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-JPM5-7XH4-QGJV", "record": "GHSA-JPM5-7XH4-QGJV", "field": "modified"}, {"timestamp": "2023-12-13T01:23:28.985Z", "date_only": false, "value": "2023-12-13T01:23:28.985540Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-28543", "record": "GSD-2021-28543", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-08-03T21:47:32.984Z", "date_only": false, "value": "2024-08-03T21:47:32.984Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "cve-2021-28543", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-08-03T21:47:32.984Z", "date_only": false, "value": "2024-08-03T21:47:32.984Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "cve-2021-28543", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2025-10-01T23:11:09Z", "date_only": false, "value": "2025-10-01T23:11:09.000Z", "kind": "other", "label": "Advisory revision", "source": "csaf_microsoft \u00b7 MSRC_CVE-2021-28543", "record": "MSRC_CVE-2021-28543", "field": "document.tracking.revision_history.0.date"}, {"timestamp": "2025-10-01T23:11:09Z", "date_only": false, "value": "2025-10-01T23:11:09.000Z", "kind": "other", "label": "Date", "source": "csaf_microsoft \u00b7 MSRC_CVE-2021-28543", "record": "MSRC_CVE-2021-28543", "field": "vulnerabilities.0.remediations.0.date"}, {"timestamp": "2025-10-01T23:11:09Z", "date_only": false, "value": "2025-10-01T23:11:09.000Z", "kind": "other", "label": "Updated", "source": "csaf_microsoft \u00b7 MSRC_CVE-2021-28543", "record": "MSRC_CVE-2021-28543", "field": "document.tracking.current_release_date"}, {"timestamp": "2025-12-27T19:04:30.583Z", "date_only": false, "value": "2025-12-27T19:04:30.583Z", "kind": "other", "label": "Document generated", "source": "csaf_microsoft \u00b7 MSRC_CVE-2021-28543", "record": "MSRC_CVE-2021-28543", "field": "document.tracking.generator.date"}, {"timestamp": "2026-06-17T03:46:30.047Z", "date_only": false, "value": "2026-06-17T03:46:30.047", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-28543", "record": "FKIE_CVE-2021-28543", "field": "lastModified"}]}
