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-2020-13649 in the wild and no public exploit code.\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-2020-13649/ (Markdown: https://insights.sbomify.com/CVE-2020-13649/index.md)","id":"CVE-2020-13649","markdown":"https://insights.sbomify.com/CVE-2020-13649/index.md","name":"CVE-2020-13649","record":{"aliases":["GHSA-47mc-x3rj-x64v","UBUNTU-CVE-2020-13649"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript engine","requires_auth":"none","summary":"Attackers can cause a denial of service in JerryScript via a null pointer dereference during out-of-memory conditions.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jerryscript","vendor":"jerryscript"}],"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-754","name":"Improper Check for Unusual or Exceptional Conditions"},{"id":"CWE-617","name":"Reachable Assertion"},{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"parser/js/js-scanner.c in JerryScript 2.2.0 mishandles errors during certain out-of-memory conditions, as demonstrated by a scanner_reverse_info_list NULL pointer dereference and a scanner_scan_all assertion failure.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Null dereference in n/a","id":"CVE-2020-13649","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jerryscript:jerryscript","products":["jerryscript:jerryscript"],"type":"null_dereference","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Server-side request forgery in n/a","id":"CVE-2020-13650"},"packages":[],"prev":{"headline":"In Cheetah free WiFi 5.1, the driver file (liebaonat.sys) allows local users to cause a denial of service (BSOD) or possibly have unspecifie","id":"CVE-2020-13646"},"products":["n/a"],"published":"2020-05-28","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-2023-38961","kev_date_added":null,"published":"2023-08-21"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in JerryScript via a null pointer dereference during out-of-memory conditions.","url":"https://insights.sbomify.com/CVE-2020-13649/"}
