It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-4300 in the wild and no public exploit code.\n\nAffected product: Libarchive Libarchive. 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-2016-4300/ (Markdown: https://insights.sbomify.com/CVE-2016-4300/index.md)","id":"CVE-2016-4300","markdown":"https://insights.sbomify.com/CVE-2016-4300/index.md","name":"CVE-2016-4300","record":{"aliases":["ALPINE-CVE-2016-4300","DEBIAN-CVE-2016-4300","GHSA-6qg7-x2gx-6jfr","UBUNTU-CVE-2016-4300"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"libarchive","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a crafted 7zip file due to an integer overflow leading to heap corruption in libarchive.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"libarchive","vendor":"libarchive"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_hpc_node","vendor":"redhat"},{"product":"enterprise_linux_hpc_node_eus","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_eus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Integer overflow in the read_SubStreamsInfo function in archive_read_support_format_7zip.c in libarchive before 3.2.1 allows remote attackers to execute arbitrary code via a 7zip file with a large number of substreams, which triggers a heap-based buffer overflow.","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":"Integer overflow in n/a","id":"CVE-2016-4300","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"libarchive:libarchive","products":["libarchive:libarchive","redhat:enterprise_linux_desktop","redhat:enterprise_linux_hpc_node","redhat:enterprise_linux_hpc_node_eus","redhat:enterprise_linux_server","redhat:enterprise_linux_server_aus","redhat:enterprise_linux_server_eus","redhat:enterprise_linux_workstation"],"type":"integer_overflow","year":"2016"},"n_packages":0,"n_references":12,"next":{"headline":"Memory corruption in n/a","id":"CVE-2016-4301"},"packages":[],"prev":{"headline":"Integer overflow in Hancom version Hancom Office 2014 VP Trial HShow.exe Product version: 9.1.0.2176 HncBM90.dll Product version: 9.1.0.2291","id":"CVE-2016-4298"},"products":["n/a"],"published":"2016-09-21","related":[{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2024-37407","kev_date_added":null,"published":"2024-06-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2016-1541","kev_date_added":null,"published":"2016-05-07"},{"cvss_score":8.6,"headline":"Integer overflow in n/a","id":"CVE-2016-6250","kev_date_added":null,"published":"2016-09-21"},{"cvss_score":7.8,"headline":"Libarchive: double free at archive_read_format_rar_seek_data() in archive_read_support_format_rar.c","id":"CVE-2025-5914","kev_date_added":null,"published":"2025-06-09"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2024-48957","kev_date_added":null,"published":"2024-10-10"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2024-48958","kev_date_added":null,"published":"2024-10-10"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via a crafted 7zip file due to an integer overflow leading to heap corruption in libarchive.","url":"https://insights.sbomify.com/CVE-2016-4300/"}
