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-2021-33938 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-2021-33938/ (Markdown: https://insights.sbomify.com/CVE-2021-33938/index.md)","id":"CVE-2021-33938","markdown":"https://insights.sbomify.com/CVE-2021-33938/index.md","name":"CVE-2021-33938","record":{"aliases":["DEBIAN-CVE-2021-33938","GHSA-h7mv-xp82-8pqc","UBUNTU-CVE-2021-33938"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libsolv package solver","requires_auth":"none","summary":"A buffer overflow in the libsolv library allows attackers to cause a denial of service condition.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libsolv","vendor":"opensuse"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Buffer overflow vulnerability in function prune_to_recommended in src/policy.c in libsolv before 0.7.17 allows attackers to cause a Denial of Service.","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":"Memory corruption in n/a","id":"CVE-2021-33938","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":"Memory corruption in n/a","id":"CVE-2021-33945"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-33930"},"products":["n/a"],"published":"2021-09-02","related":[{"cvss_score":7.8,"headline":"Libsolv: heap buffer overflow in libsolv repopagestore via unchecked decompression of malicious .solv page data","id":"CVE-2026-48864","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-33928","kev_date_added":null,"published":"2021-09-02"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-33929","kev_date_added":null,"published":"2021-09-02"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-33930","kev_date_added":null,"published":"2021-09-02"},{"cvss_score":6.5,"headline":"Libsolv: heap buffer overflow in libsolv repo_add_solv via negative maxsize from crafted .solv file","id":"CVE-2026-9149","kev_date_added":null,"published":"2026-05-20"},{"cvss_score":6.5,"headline":"Libsolv: stack-based buffer overflow in libsolv's debian metadata parser when handling sha384/sha512 checksums","id":"CVE-2026-9150","kev_date_added":null,"published":"2026-05-20"}],"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 buffer overflow in the libsolv library allows attackers to cause a denial of service condition.","url":"https://insights.sbomify.com/CVE-2021-33938/"}
