An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-35862 exists.\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-2023-35862/ (Markdown: https://insights.sbomify.com/CVE-2023-35862/index.md)","id":"CVE-2023-35862","markdown":"https://insights.sbomify.com/CVE-2023-35862/index.md","name":"CVE-2023-35862","record":{"aliases":["GHSA-84qc-gm86-22q4","UBUNTU-CVE-2023-35862"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"CoAP protocol library","requires_auth":"none","summary":"A buffer over-read in libcoap allows attackers to cause denial of service or disclose sensitive memory contents.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libcoap","vendor":"libcoap"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"libcoap 4.3.1 contains a buffer over-read via the function coap_parse_oscore_conf_mem at coap_oscore.c.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Memory corruption in n/a","id":"CVE-2023-35862","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Race condition in n/a","id":"CVE-2023-35863"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2023-35861"},"products":["n/a"],"published":"2023-06-19","related":[{"cvss_score":8.8,"headline":"libcoap Out-of-Bounds Read in OSCORE CBOR Unwrap Handling","id":"CVE-2026-29013","kev_date_added":null,"published":"2026-04-17"},{"cvss_score":8.2,"headline":"libcoap Stack-Based Buffer Overflow in Address Resolution DoS or Potential RCE","id":"CVE-2025-34468","kev_date_added":null,"published":"2025-12-31"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2025-65493","kev_date_added":null,"published":"2025-11-24"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2025-65494","kev_date_added":null,"published":"2025-11-24"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2025-65495","kev_date_added":null,"published":"2025-11-24"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2023-30362","kev_date_added":null,"published":"2023-06-23"},{"cvss_score":6.5,"headline":"Information disclosure in n/a","id":"CVE-2025-59391","kev_date_added":null,"published":"2025-12-08"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-12-11","vendors":["n/a"]},"summary":"A buffer over-read in libcoap allows attackers to cause denial of service or disclose sensitive memory contents.","url":"https://insights.sbomify.com/CVE-2023-35862/"}
