{"id":"UBUNTU-CVE-2025-5916","details":"A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4 content bytes. An attacker could craft a malicious WARC archive to induce this overflow, potentially leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within applications that process such archives using libarchive. This bug affects libarchive versions prior to 3.8.0.","modified":"2026-04-22T16:07:25.920948Z","published":"2025-06-09T20:15:00Z","related":["USN-7601-1","USN-8147-1"],"upstream":["CVE-2025-5916"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-5916"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-5916"},{"type":"REPORT","url":"https://github.com/libarchive/libarchive/pull/2568"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2025-5916"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2370872"},{"type":"REPORT","url":"https://github.com/libarchive/libarchive/releases/tag/v3.8.0"},{"type":"REPORT","url":"https://github.com/libarchive/libarchive/pull/2568/commits/bce70c4c26864df2a8d6953e7db6e4b156253508"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7601-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8147-1"}],"affected":[{"package":{"name":"libarchive","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/libarchive@3.1.2-7ubuntu2.8+esm4?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.2-7ubuntu2.8+esm4"}]}],"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"],"ecosystem_specific":{"availability":"Available
