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-2016-8618 in the wild and no public exploit code.\n\nAffected product: Haxx Curl. 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-2016-8618/ (Markdown: https://insights.sbomify.com/CVE-2016-8618/index.md)","id":"CVE-2016-8618","markdown":"https://insights.sbomify.com/CVE-2016-8618/index.md","name":"CVE-2016-8618","record":{"aliases":["ALPINE-CVE-2016-8618","CLEANSTART-2026-KM83938","CURL-CVE-2016-8618","DEBIAN-CVE-2016-8618","GHSA-36jj-p27h-fh24","UBUNTU-CVE-2016-8618"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"curl library","requires_auth":"none","summary":"A double-free vulnerability in libcurl's curl_maprintf function on 32-bit systems allows attackers to cause denial of service or execute arbitrary code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"curl","vendor":"haxx"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-415","name":"Double Free"},{"id":"CWE-416","name":"Use After Free"}],"description":"The libcurl API function called `curl_maprintf()` before version 7.51.0 can be tricked into doing a double-free due to an unsafe `size_t` multiplication, on systems using 32 bit `size_t` variables.","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":"Use after free in curl","id":"CVE-2016-8618","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"haxx:curl","products":["haxx:curl"],"type":"use_after_free","year":"2016"},"n_packages":0,"n_references":9,"next":{"headline":"Use after free in curl","id":"CVE-2016-8619"},"packages":[],"prev":{"headline":"Memory corruption in curl","id":"CVE-2016-8617"},"products":["curl"],"published":"2018-07-31","related":[{"cvss_score":9.8,"headline":"Negotiate ambient user conn reuse","id":"CVE-2026-19931","kev_date_added":null,"published":"2026-09-06"},{"cvss_score":9.8,"headline":"HTTP/2 stream-dependency tree UAF","id":"CVE-2026-10536","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"cross-origin Digest auth state leak","id":"CVE-2026-11856","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"SASL double-free","id":"CVE-2026-8925","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"stale proxy password leak","id":"CVE-2026-9079","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"Code injection in curl","id":"CVE-2016-4606","kev_date_added":null,"published":"2020-02-21"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2016-9953","kev_date_added":null,"published":"2018-03-12"}],"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":["The Curl Project"]},"summary":"A double-free vulnerability in libcurl's curl_maprintf function on 32-bit systems allows attackers to cause denial of service or execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2016-8618/"}
