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-2018-4281 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-2018-4281/ (Markdown: https://insights.sbomify.com/CVE-2018-4281/index.md)","id":"CVE-2018-4281","markdown":"https://insights.sbomify.com/CVE-2018-4281/index.md","name":"CVE-2018-4281","record":{"aliases":["GHSA-rx5q-753m-6mmq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SwiftNIO library","requires_auth":"none","summary":"A buffer overflow in SwiftNIO allows attackers to execute arbitrary code or cause denial of service via improved size validation fixes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apple","cpe":[{"product":"swiftnio","vendor":"apple"}],"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":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"In SwiftNIO before 1.8.0, a buffer overflow was addressed with improved size validation.","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":"Memory corruption in n/a","id":"CVE-2018-4281","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in iOS, tvOS, watchOS","id":"CVE-2018-4282"},"packages":[],"prev":{"headline":"Memory corruption in iOS, macOS, tvOS, watchOS","id":"CVE-2018-4280"},"products":["n/a"],"published":"2019-01-11","related":[{"cvss_score":7.5,"headline":"SwiftNIO vulnerable to Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')","id":"CVE-2022-3215","kev_date_added":null,"published":"2022-09-28"},{"cvss_score":5.3,"headline":"Denial of service in swift-nio","id":"CVE-2026-43678","kev_date_added":null,"published":"2026-08-20"}],"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":"A buffer overflow in SwiftNIO allows attackers to execute arbitrary code or cause denial of service via improved size validation fixes.","url":"https://insights.sbomify.com/CVE-2018-4281/"}
