An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-7835 in the wild and no public exploit code.\n\nAffected product: Kazuho Oku H2O. 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-2016-7835/ (Markdown: https://insights.sbomify.com/CVE-2016-7835/index.md)","id":"CVE-2016-7835","markdown":"https://insights.sbomify.com/CVE-2016-7835/index.md","name":"CVE-2016-7835","record":{"aliases":["GHSA-p8m4-qhm5-5gm6"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"H2O web server","requires_auth":"none","summary":"Remote attackers can trigger a use-after-free in H2O to cause denial of service or steal server certificate private keys.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"h2o","vendor":"dena"},{"product":"h2o","vendor":"h2o_project"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use-after-free vulnerability in H2O allows remote attackers to cause a denial-of-service (DoS) or obtain server certificate private keys and possibly other information.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Use after free in H2O","id":"CVE-2016-7835","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2016"},"n_packages":0,"n_references":3,"next":{"headline":"SKYSEA Client View Improper Authentication","id":"CVE-2016-7836"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2016-7834"},"products":["H2O"],"published":"2017-06-09","related":[{"cvss_score":9.8,"headline":"Memory corruption in H2O","id":"CVE-2018-0608","kev_date_added":null,"published":"2018-06-26"},{"cvss_score":8.2,"headline":"H2O vulnerable to read from uninitialized pointer in the reverse proxy handler","id":"CVE-2023-30847","kev_date_added":null,"published":"2023-04-27"},{"cvss_score":7.5,"headline":"Denial of service in H2O","id":"CVE-2017-10868","kev_date_added":null,"published":"2017-12-22"},{"cvss_score":7.5,"headline":"Memory corruption in H2O","id":"CVE-2017-10869","kev_date_added":null,"published":"2017-12-22"},{"cvss_score":7.5,"headline":"Denial of service in H2O","id":"CVE-2017-10908","kev_date_added":null,"published":"2017-12-22"},{"cvss_score":7.5,"headline":"Denial of service in H2O","id":"CVE-2016-4864","kev_date_added":null,"published":"2017-05-12"}],"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":"2024-08-06","vendors":["Kazuho Oku"]},"summary":"Remote attackers can trigger a use-after-free in H2O to cause denial of service or steal server certificate private keys.","url":"https://insights.sbomify.com/CVE-2016-7835/"}
