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-2021-30045 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-2021-30045/ (Markdown: https://insights.sbomify.com/CVE-2021-30045/index.md)","id":"CVE-2021-30045","markdown":"https://insights.sbomify.com/CVE-2021-30045/index.md","name":"CVE-2021-30045","record":{"aliases":["GHSA-6m2h-c4q5-c6rp"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SerenityOS","requires_auth":"none","summary":"A buffer overflow in SerenityOS allows attackers to execute arbitrary code or cause a denial of service via crafted input.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"serenityos","vendor":"serenityos"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"SerenityOS 2021-03-27 contains a buffer overflow vulnerability in the EndOfCentralDirectory::read() function.","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-2021-30045","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-30046"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-30044"},"products":["n/a"],"published":"2021-04-06","related":[{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2021-31272","kev_date_added":null,"published":"2021-06-18"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2021-28874","kev_date_added":null,"published":"2021-04-06"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2019-20172","kev_date_added":null,"published":"2019-12-31"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-33185","kev_date_added":null,"published":"2021-06-18"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-33186","kev_date_added":null,"published":"2021-06-18"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-27343","kev_date_added":null,"published":"2021-04-06"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"A buffer overflow in SerenityOS allows attackers to execute arbitrary code or cause a denial of service via crafted input.","url":"https://insights.sbomify.com/CVE-2021-30045/"}
