It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-39552 and fix it if it is affected.\n\nWhat it is: CVE-2021-39552 is a high-severity memory corruption vulnerability in n/a, published on 20 Sep 2021. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-39552 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-2021-39552/ (Markdown: https://insights.sbomify.com/CVE-2021-39552/index.md)","id":"CVE-2021-39552","markdown":"https://insights.sbomify.com/CVE-2021-39552/index.md","name":"CVE-2021-39552","record":{"aliases":["GHSA-x9h5-7586-77cw"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"sela audio library","requires_auth":"none","summary":"A heap-based buffer overflow in the sela library allows attackers to execute arbitrary code or cause denial of service via crafted WAV files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"sela","vendor":"sela_project"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An issue was discovered in sela through 20200412. file::WavFile::readFromFile() in wav_file.c has a heap-based buffer overflow.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2021-39552","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in n/a","id":"CVE-2021-39553"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-39551"},"products":["n/a"],"published":"2021-09-20","related":[{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2021-39544","kev_date_added":null,"published":"2021-09-20"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2021-39546","kev_date_added":null,"published":"2021-09-20"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2021-39550","kev_date_added":null,"published":"2021-09-20"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2021-39551","kev_date_added":null,"published":"2021-09-20"},{"cvss_score":5.5,"headline":"Null dereference in n/a","id":"CVE-2021-39545","kev_date_added":null,"published":"2021-09-20"},{"cvss_score":5.5,"headline":"Null dereference in n/a","id":"CVE-2021-39547","kev_date_added":null,"published":"2021-09-20"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A heap-based buffer overflow in the sela library allows attackers to execute arbitrary code or cause denial of service via crafted WAV files.","url":"https://insights.sbomify.com/CVE-2021-39552/"}
