It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-1581 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2016-1581/ (Markdown: https://insights.sbomify.com/CVE-2016-1581/index.md)","id":"CVE-2016-1581","markdown":"https://insights.sbomify.com/CVE-2016-1581/index.md","name":"CVE-2016-1581","record":{"aliases":["UBUNTU-CVE-2016-1581"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"LXD container manager","requires_auth":"low_privilege","summary":"Local users can read arbitrary container data due to world-readable permissions on the ZFS image file in LXD.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"lxd","vendor":"canonical"},{"product":"ubuntu_linux","vendor":"canonical"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"LXD before 2.0.2 uses world-readable permissions for /var/lib/lxd/zfs.img when setting up a loop based ZFS pool, which allows local users to copy and read data from arbitrary containers via unspecified vectors.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Information disclosure in n/a","id":"CVE-2016-1581","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux"],"type":"information_disclosure","year":"2016"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2016-1582"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2016-1580"},"products":["n/a"],"published":"2016-06-09","related":[{"cvss_score":9.9,"headline":"Instance template path traversal allows arbitrary host file write as root","id":"CVE-2026-66897","kev_date_added":null,"published":"2026-08-24"},{"cvss_score":9.9,"headline":"Cross-project cluster migration bypasses project restrictions via cluster notification flag","id":"CVE-2026-62420","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Arbitrary File Read/Write: metadata.yaml symlink in image allows host filesystem access as root","id":"CVE-2026-63293","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Root RCE via image backup.yaml symlink","id":"CVE-2026-63294","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Project restriction bypass via instance migration config override","id":"CVE-2026-63296","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Cross-project instance copy bypasses target project restrictions via TOCTOU in config merge","id":"CVE-2026-63297","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.9,"headline":"Cross-project instance move bypasses all project restrictions allowing host command execution","id":"CVE-2026-63300","kev_date_added":null,"published":"2026-08-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Local users can read arbitrary container data due to world-readable permissions on the ZFS image file in LXD.","url":"https://insights.sbomify.com/CVE-2016-1581/"}
