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-2019-20792 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-2019-20792/ (Markdown: https://insights.sbomify.com/CVE-2019-20792/index.md)","id":"CVE-2019-20792","markdown":"https://insights.sbomify.com/CVE-2019-20792/index.md","name":"CVE-2019-20792","record":{"aliases":["DEBIAN-CVE-2019-20792","GHSA-m2w8-wqfw-qchx","UBUNTU-CVE-2019-20792","openSUSE-SU-2024:11643-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenSC smart card library","requires_auth":"none","summary":"A double free vulnerability in OpenSC allows attackers to potentially execute arbitrary code or cause a denial of service via crafted smart card data.","user_interaction":"not_required","vuln_class":"use_after_free"},"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:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"OpenSC before 0.20.0 has a double free in coolkey_free_private_data because coolkey_add_object in libopensc/card-coolkey.c lacks a uniqueness check.","ecosystems":["openSUSE:Tumbleweed"],"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":"Use after free in n/a","id":"CVE-2019-20792","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"opensc_project:opensc","products":["opensc_project:opensc"],"type":"use_after_free","year":"2019"},"n_packages":1,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2019-20794"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["0.22.0-3.1"],"introduced":["0"],"last_affected":[],"package":"opensc","purl":"pkg:rpm/opensuse/opensc\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11643-1"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2019-20791"},"products":["n/a"],"published":"2020-04-29","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":"Memory corruption in n/a","id":"CVE-2018-16391","kev_date_added":null,"published":"2018-09-03"},{"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":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"A double free vulnerability in OpenSC allows attackers to potentially execute arbitrary code or cause a denial of service via crafted smart card data.","url":"https://insights.sbomify.com/CVE-2019-20792/"}
