{"id":"CVE-2025-64031","details":"libarchive 3.8.x before 3.8.2 has a strcpy heap-based buffer overflow in the gzip writer via the original-filename field to archive_compressor_gzip_open in archive_write_add_filter_gzip.c, aka GHSA-92wx-p669-8gr9. This relates to bsdtar. Exploitation envisions a marginally plausible scenario in which original-filename is obtained from an untrusted party. (original-filename is not derived from the input data.)","modified":"2026-09-17T03:30:28.827740045Z","published":"2026-09-14T00:00:00Z","database_specific":{"cwe_ids":["CWE-122"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/64xxx/CVE-2025-64031.json","cna_assigner":"mitre"},"references":[{"type":"WEB","url":"https://gist.github.com/ttuurrnn/1365a4a9b1c3d5826a3a9bbe111f26b8"},{"type":"WEB","url":"https://github.com/libarchive/libarchive/blob/master/libarchive/archive_write_add_filter_gzip.c"},{"type":"WEB","url":"https://github.com/libarchive/libarchive/pull/2734/commits"},{"type":"WEB","url":"https://github.com/libarchive/libarchive/pull/2734/files"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/64xxx/CVE-2025-64031.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-64031"},{"type":"FIX","url":"https://github.com/libarchive/libarchive/pull/2734"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/libarchive/libarchive","events":[{"introduced":"70ff28fcf04ec129a1d064f96e49aa57fcc90e37"},{"fixed":"7f53fce04e4e672230f4eb80b219af17975e4f83"}],"database_specific":{"extracted_events":[{"introduced":"3.8.0"},{"fixed":"3.8.2"},{"introduced":"3.8.x"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v3.8.1","v3.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-64031.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L"}]}
