An attacker can cause a Denial of Service (DoS) or potential information disclosure due to a use-after-free vulnerability, which occurs when a program reads memory that has already been released. This issue arises when the archive_entry_copy_mac_metadata() function deallocates an internal buffer before completing a data copy. An attacker who can supply input to an application utilizing this function can trigger the flaw to crash the application or read uninitialized memory data.\nhttps://www.cve.org/CVERecord?id=CVE-2026-17591https://access.redhat.com/security/cve/CVE-2026-17591https://bugzilla.redhat.com/show_bug.cgi?id=2554209https://github.com/libarchive/libarchive/pull/3318#RedHat #RedHatEnterpriseLinux10 #RedHatEnterpriseLinux6 #RedHatEnterpriseLinux7 #RedHatEnterpriseLinux8 #RedHatEnterpriseLinux9 #RedHatHardenedImages#CVE_2026_17591#bot", "url": "https://infosec.exchange/users/cve/statuses/117452940293969680"}, {"timestamp": "2026-10-16T23:17:01Z", "date_only": false, "value": "2026-10-16T23:17:01Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-X7V4-6QHP-JG74", "record": "GHSA-X7V4-6QHP-JG74", "field": "database_specific.nvd_published_at"}, {"timestamp": "2026-10-16T23:17:01.420Z", "date_only": false, "value": "2026-10-16T23:17:01.420", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-17591", "record": "FKIE_CVE-2026-17591", "field": "published"}, {"timestamp": "2026-10-17T00:31:19Z", "date_only": false, "value": "2026-10-17T00:31:19Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-X7V4-6QHP-JG74", "record": "GHSA-X7V4-6QHP-JG74", "field": "published"}, {"timestamp": "2026-10-17T15:09:28Z", "date_only": false, "value": "2026-10-17T15:09:28+00:00", "kind": "other", "label": "Advisory revision", "source": "csaf_redhat \u00b7 RHSA-2026:77775", "record": "RHSA-2026:77775", "field": "document.tracking.revision_history.1.date"}, {"timestamp": "2026-10-17T16:50:55Z", "date_only": false, "value": "2026-10-17T16:50:55+00:00", "kind": "other", "label": "Advisory revision", "source": "csaf_redhat \u00b7 RHSA-2026:77775", "record": "RHSA-2026:77775", "field": "document.tracking.revision_history.2.date"}, {"timestamp": "2026-10-17T16:50:55Z", "date_only": false, "value": "2026-10-17T16:50:55+00:00", "kind": "other", "label": "Document generated", "source": "csaf_redhat \u00b7 RHSA-2026:77775", "record": "RHSA-2026:77775", "field": "document.tracking.generator.date"}, {"timestamp": "2026-10-17T16:50:55Z", "date_only": false, "value": "2026-10-17T16:50:55+00:00", "kind": "other", "label": "Updated", "source": "csaf_redhat \u00b7 RHSA-2026:77775", "record": "RHSA-2026:77775", "field": "document.tracking.current_release_date"}, {"timestamp": "2026-10-17T16:50:55.660Z", "date_only": false, "value": "2026-10-17T16:50:55.660Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / redhat", "record": "CVE-2026-17591", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-17T18:31:08Z", "date_only": false, "value": "2026-10-17T18:31:08Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-X7V4-6QHP-JG74", "record": "GHSA-X7V4-6QHP-JG74", "field": "modified"}, {"timestamp": "2026-10-19T21:27:56.253Z", "date_only": false, "value": "2026-10-19T21:27:56.253609Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-17591", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-19T21:27:56.253Z", "date_only": false, "value": "2026-10-19T21:27:56.253609Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-17591", "record": "FKIE_CVE-2026-17591", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-10-19T21:28:22.621Z", "date_only": false, "value": "2026-10-19T21:28:22.621Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-17591", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-19T21:28:22.621Z", "date_only": false, "value": "2026-10-19T21:28:22.621Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-17591", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-19T22:17:10.423Z", "date_only": false, "value": "2026-10-19T22:17:10.423", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-17591", "record": "FKIE_CVE-2026-17591", "field": "lastModified"}]}
