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-2016-6873 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2016-6873/ (Markdown: https://insights.sbomify.com/CVE-2016-6873/index.md)","id":"CVE-2016-6873","markdown":"https://insights.sbomify.com/CVE-2016-6873/index.md","name":"CVE-2016-6873","record":{"aliases":["GHSA-hj8w-h393-6h4r","UBUNTU-CVE-2016-6873"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"HHVM runtime","requires_auth":"none","summary":"Attackers can cause a denial of service in HHVM via self-recursion in the compact function, requiring an upgrade to mitigate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"hhvm","vendor":"facebook"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"Self recursion in compact in Facebook HHVM before 3.15.0 allows attackers to have unspecified impact via unknown 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":false,"headline":"Denial of service in n/a","id":"CVE-2016-6873","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":3,"next":{"headline":"The array_*_recursive functions in Facebook HHVM before 3.15.0 allows attackers to have unspecified impact via unknown vectors, related to recursion.","id":"CVE-2016-6874"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2016-6872"},"products":["n/a"],"published":"2017-02-17","related":[{"cvss_score":9.8,"headline":"HHVM 4.172.0 and all prior versions use TLS 1.0 for secure connections when handling tls:// URLs in the stream extension.","id":"CVE-2022-36937","kev_date_added":null,"published":"2023-05-10"},{"cvss_score":9.8,"headline":"Use after free in HHVM","id":"CVE-2020-1900","kev_date_added":null,"published":"2021-03-11"},{"cvss_score":9.8,"headline":"Integer overflow in HHVM","id":"CVE-2020-1916","kev_date_added":null,"published":"2021-03-10"},{"cvss_score":9.8,"headline":"Memory corruption in HHVM","id":"CVE-2020-1917","kev_date_added":null,"published":"2021-03-10"},{"cvss_score":9.8,"headline":"Integer overflow in HHVM","id":"CVE-2021-24025","kev_date_added":null,"published":"2021-03-10"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2016-1000004","kev_date_added":null,"published":"2020-02-19"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2016-1000005","kev_date_added":null,"published":"2020-02-19"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in HHVM via self-recursion in the compact function, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2016-6873/"}
