When libreswan decodes an IKE CERT payload of type CERT_PKCS7_WRAPPED_X509, it guards the PKCS#7 blob with SEC_PKCS7ContainsCertsOrCrls() and then iterates the certificate list with SEC_PKCS7GetCertificateList(). The two NSS APIs disagree on a SignedData that carries a CRL but no certificates: ContainsCertsOrCrls() returns PR_TRUE (there is a CRL), so the guard passes, but GetCertificateList() returns NULL (there are no certificates). This causes libreswan to dereference a null pointer leading to a crash and restart. A malicious IKE_AUTH packet can trigger this bug, meaning the peer does not need to be authenticated. No remote code execution is possible. Continued exploitation can cause a denial of service.\nhttps://www.cve.org/CVERecord?id=CVE-2026-77207https://libreswan.org/security/CVE-2026-77207/CVE-2026-77207.txthttps://libreswan.org/security/CVE-2026-77207/#libreswan #TheLibreswanProject#CVE_2026_77207#bot", "url": "https://infosec.exchange/users/cve/statuses/117440105727271162"}, {"timestamp": "2026-10-15T01:08:58Z", "date_only": false, "value": "2026-10-15T01:08:58.000Z", "kind": "other", "label": "Advisory revision", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-77207", "record": "MSRC_CVE-2026-77207", "field": "document.tracking.revision_history.0.date"}, {"timestamp": "2026-10-15T01:08:58Z", "date_only": false, "value": "2026-10-15T01:08:58.000Z", "kind": "other", "label": "Date", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-77207", "record": "MSRC_CVE-2026-77207", "field": "vulnerabilities.0.remediations.0.date"}, {"timestamp": "2026-10-15T01:08:58Z", "date_only": false, "value": "2026-10-15T01:08:58.000Z", "kind": "milestone", "label": "Published", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-77207", "record": "MSRC_CVE-2026-77207", "field": "document.tracking.initial_release_date"}, {"timestamp": "2026-10-15T01:08:58Z", "date_only": false, "value": "2026-10-15T01:08:58.000Z", "kind": "other", "label": "Updated", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-77207", "record": "MSRC_CVE-2026-77207", "field": "document.tracking.current_release_date"}, {"timestamp": "2026-10-15T07:01:21.023Z", "date_only": false, "value": "2026-10-15T07:01:21.023Z", "kind": "other", "label": "Document generated", "source": "csaf_microsoft \u00b7 MSRC_CVE-2026-77207", "record": "MSRC_CVE-2026-77207", "field": "document.tracking.generator.date"}]}
