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-2020-24334 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-2020-24334/ (Markdown: https://insights.sbomify.com/CVE-2020-24334/index.md)","id":"CVE-2020-24334","markdown":"https://insights.sbomify.com/CVE-2020-24334/index.md","name":"CVE-2020-24334","record":{"aliases":["GHSA-38jp-4v3p-cc3q"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Contiki uIP stack","requires_auth":"none","summary":"Attackers can cause a denial of service in Contiki devices by sending malformed DNS responses that trigger an out-of-bounds read in the uIP stack.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"uip","vendor":"uip_project"}],"cvss":{"score":8.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"The code that processes DNS responses in uIP through 1.0, as used in Contiki and Contiki-NG, does not check whether the number of responses specified in the DNS packet header corresponds to the response data available in the DNS packet, leading to an out-of-bounds read and Denial-of-Service in resolv.c.","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-2020-24334","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-24335"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2020-24333"},"products":["n/a"],"published":"2020-12-11","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-17438","kev_date_added":null,"published":"2020-12-11"},{"cvss_score":8.3,"headline":"Other in n/a","id":"CVE-2020-17439","kev_date_added":null,"published":"2020-12-11"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2020-24335","kev_date_added":null,"published":"2021-02-02"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2020-17440","kev_date_added":null,"published":"2020-12-11"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in Contiki devices by sending malformed DNS responses that trigger an out-of-bounds read in the uIP stack.","url":"https://insights.sbomify.com/CVE-2020-24334/"}
