An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-38961 exists.\n\nAffected product: Jerryscript Jerryscript. 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-2023-38961/ (Markdown: https://insights.sbomify.com/CVE-2023-38961/index.md)","id":"CVE-2023-38961","markdown":"https://insights.sbomify.com/CVE-2023-38961/index.md","name":"CVE-2023-38961","record":{"aliases":["GHSA-9w63-m7q9-mjhm","UBUNTU-CVE-2023-38961"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript engine library","requires_auth":"none","summary":"A buffer overflow in the JerryScript JavaScript engine allows remote attackers to execute arbitrary code via the scanner component.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jerryscript","vendor":"jerryscript"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Buffer Overflwo vulnerability in JerryScript Project jerryscript v.3.0.0 allows a remote attacker to execute arbitrary code via the scanner_is_context_needed component in js-scanner-until.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-2023-38961","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jerryscript:jerryscript","products":["jerryscript:jerryscript"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2023-38964"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2023-38960"},"products":["n/a"],"published":"2023-08-21","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-36109","kev_date_added":null,"published":"2023-09-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-22597","kev_date_added":null,"published":"2023-07-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-42863","kev_date_added":null,"published":"2022-05-12"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-43453","kev_date_added":null,"published":"2022-04-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-41751","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2021-41752","kev_date_added":null,"published":"2022-04-05"}],"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-07","vendors":["n/a"]},"summary":"A buffer overflow in the JerryScript JavaScript engine allows remote attackers to execute arbitrary code via the scanner component.","url":"https://insights.sbomify.com/CVE-2023-38961/"}
