It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-16391 in the wild and no public exploit code.\n\nAffected product: Opensc Project Opensc. 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-2018-16391/ (Markdown: https://insights.sbomify.com/CVE-2018-16391/index.md)","id":"CVE-2018-16391","markdown":"https://insights.sbomify.com/CVE-2018-16391/index.md","name":"CVE-2018-16391","record":{"aliases":["CVE-2018-1000672","DEBIAN-CVE-2018-16391","GHSA-37c8-gm6x-ffch","UBUNTU-CVE-2018-16391"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenSC smartcard library","requires_auth":"none","summary":"Buffer overflows in OpenSC allow attackers with crafted smartcards to cause application crashes or potential other impacts.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"opensc","vendor":"opensc_project"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Several buffer overflows when handling responses from a Muscle Card in muscle_list_files in libopensc/card-muscle.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.","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-2018-16391","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"opensc_project:opensc","products":["opensc_project:opensc"],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2018-16392"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2018-16389"},"products":["n/a"],"published":"2018-09-03","related":[{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-34193","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2019-16058","kev_date_added":null,"published":"2019-09-06"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2019-6502","kev_date_added":null,"published":"2019-01-22"},{"cvss_score":7.1,"headline":"Memory corruption in OpenSC","id":"CVE-2023-2977","kev_date_added":null,"published":"2023-06-01"},{"cvss_score":6.8,"headline":"Use after free in n/a","id":"CVE-2019-20792","kev_date_added":null,"published":"2020-04-29"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2018-16392","kev_date_added":null,"published":"2018-09-03"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Buffer overflows in OpenSC allow attackers with crafted smartcards to cause application crashes or potential other impacts.","url":"https://insights.sbomify.com/CVE-2018-16391/"}
