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-2020-20658 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-2020-20658/ (Markdown: https://insights.sbomify.com/CVE-2020-20658/index.md)","id":"CVE-2020-20658","markdown":"https://insights.sbomify.com/CVE-2020-20658/index.md","name":"CVE-2020-20658","record":{"aliases":["GHSA-24m2-vhhc-392c"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libiec_iccp_mod library","requires_auth":"none","summary":"A buffer overflow in libiec_iccp_mod allows attackers to cause a denial of service by triggering an unexpectedly large memory allocation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libiec_iccp_mod","vendor":"libiec_iccp_mod_project"}],"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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer overflow vulnerability in fcovatti libiec_iccp_mod v1.5, allows attackers to cause a denail of service when trying to calloc an unexpectiedly large space.","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":"Memory corruption in n/a","id":"CVE-2020-20658","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-20662"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-20657"},"products":["n/a"],"published":"2021-11-02","related":[{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2020-20657","kev_date_added":null,"published":"2021-11-02"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2020-20490","kev_date_added":null,"published":"2021-08-31"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2020-20662","kev_date_added":null,"published":"2021-09-30"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2020-20663","kev_date_added":null,"published":"2021-09-30"},{"cvss_score":6.5,"headline":"Null dereference in n/a","id":"CVE-2020-20664","kev_date_added":null,"published":"2021-09-30"}],"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 libiec_iccp_mod allows attackers to cause a denial of service by triggering an unexpectedly large memory allocation.","url":"https://insights.sbomify.com/CVE-2020-20658/"}
