{"id":"UBUNTU-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.

data.)","modified":"2026-09-16T11:29:58Z","published":"2026-09-14T01:16:00Z","upstream":["CVE-2025-64031"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-64031"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-64031"},{"type":"REPORT","url":"https://github.com/libarchive/libarchive/pull/2734"},{"type":"REPORT","url":"https://gist.github.com/ttuurrnn/1365a4a9b1c3d5826a3a9bbe111f26b8"},{"type":"REPORT","url":"https://github.com/libarchive/libarchive/blob/master/libarchive/archive_write_add_filter_gzip.c"},{"type":"REPORT","url":"https://github.com/libarchive/libarchive/pull/2734/commits"},{"type":"REPORT","url":"https://github.com/libarchive/libarchive/pull/2734/files"}],"affected":[{"package":{"name":"libarchive","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/libarchive?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.2-5ubuntu1","3.1.2-7ubuntu1","3.1.2-7ubuntu2","3.1.2-7ubuntu2.1","3.1.2-7ubuntu2.2","3.1.2-7ubuntu2.3","3.1.2-7ubuntu2.4","3.1.2-7ubuntu2.6","3.1.2-7ubuntu2.7","3.1.2-7ubuntu2.8","3.1.2-7ubuntu2.8+esm1","3.1.2-7ubuntu2.8+esm3","3.1.2-7ubuntu2.8+esm4","3.1.2-7ubuntu2.8+esm5"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.2-7ubuntu2.8+esm5","binary_name":"bsdcpio"},{"binary_version":"3.1.2-7ubuntu2.8+esm5","binary_name":"bsdtar"},{"binary_version":"3.1.2-7ubuntu2.8+esm5","binary_name":"libarchive13"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-64031.json"}},{"package":{"name":"libarchive","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/libarchive?arch=source&distro=esm-infra-legacy%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.2-11build1","3.1.2-11ubuntu0.16.04.1","3.1.2-11ubuntu0.16.04.2","3.1.2-11ubuntu0.16.04.3","3.1.2-11ubuntu0.16.04.4","3.1.2-11ubuntu0.16.04.5","3.1.2-11ubuntu0.16.04.6","3.1.2-11ubuntu0.16.04.7","3.1.2-11ubuntu0.16.04.8","3.1.2-11ubuntu0.16.04.8+esm1","3.1.2-11ubuntu0.16.04.8+esm2","3.1.2-11ubuntu0.16.04.8+esm3"],"ecosystem_specific":{"binaries":[{"binary_name":"bsdcpio","binary_version":"3.1.2-11ubuntu0.16.04.8+esm3"},{"binary_version":"3.1.2-11ubuntu0.16.04.8+esm3","binary_name":"bsdtar"},{"binary_version":"3.1.2-11ubuntu0.16.04.8+esm3","binary_name":"libarchive13"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-64031.json"}},{"package":{"name":"libarchive","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/libarchive?arch=source&distro=esm-infra%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.2-3.1","3.2.2-3.1ubuntu0.1","3.2.2-3.1ubuntu0.2","3.2.2-3.1ubuntu0.3","3.2.2-3.1ubuntu0.4","3.2.2-3.1ubuntu0.5","3.2.2-3.1ubuntu0.6","3.2.2-3.1ubuntu0.7","3.2.2-3.1ubuntu0.7+esm1","3.2.2-3.1ubuntu0.7+esm2","3.2.2-3.1ubuntu0.7+esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"3.2.2-3.1ubuntu0.7+esm3","binary_name":"bsdcpio"},{"binary_name":"bsdtar","binary_version":"3.2.2-3.1ubuntu0.7+esm3"},{"binary_version":"3.2.2-3.1ubuntu0.7+esm3","binary_name":"libarchive-tools"},{"binary_version":"3.2.2-3.1ubuntu0.7+esm3","binary_name":"libarchive13"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-64031.json"}},{"package":{"name":"libarchive","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/libarchive?arch=source&distro=esm-infra%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.0-1","3.4.0-1build1","3.4.0-1ubuntu2","3.4.0-2ubuntu1","3.4.0-2ubuntu1.1","3.4.0-2ubuntu1.2","3.4.0-2ubuntu1.3","3.4.0-2ubuntu1.4","3.4.0-2ubuntu1.5","3.4.0-2ubuntu1.5+esm1","3.4.0-2ubuntu1.5+esm2","3.4.0-2ubuntu1.5+esm3"],"ecosystem_specific":{"binaries":[{"binary_name":"libarchive-tools","binary_version":"3.4.0-2ubuntu1.5+esm3"},{"binary_version":"3.4.0-2ubuntu1.5+esm3","binary_name":"libarchive13"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-64031.json"}},{"package":{"name":"libarchive","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libarchive?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.3-2","3.4.3-2build1","3.5.2-1","3.5.2-1ubuntu1","3.6.0-1ubuntu1","3.6.0-1ubuntu1.1","3.6.0-1ubuntu1.2","3.6.0-1ubuntu1.3","3.6.0-1ubuntu1.4","3.6.0-1ubuntu1.5","3.6.0-1ubuntu1.6","3.6.0-1ubuntu1.7","3.6.0-1ubuntu1.8"],"ecosystem_specific":{"binaries":[{"binary_name":"libarchive-tools","binary_version":"3.6.0-1ubuntu1.8"},{"binary_name":"libarchive13","binary_version":"3.6.0-1ubuntu1.8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-64031.json"}},{"package":{"name":"libarchive","
