An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-6613 in the wild and no public exploit code.\n\nAffected product: Gnu Libredwg. 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-2020-6613/ (Markdown: https://insights.sbomify.com/CVE-2020-6613/index.md)","id":"CVE-2020-6613","markdown":"https://insights.sbomify.com/CVE-2020-6613/index.md","name":"CVE-2020-6613","record":{"aliases":["GHSA-qxg2-qjfr-5899"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"DWG file library","requires_auth":"none","summary":"A heap-based buffer over-read in GNU LibreDWG allows attackers to cause denial of service or disclose sensitive memory contents via crafted DWG files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libredwg","vendor":"gnu"},{"product":"backports_sle","vendor":"opensuse"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in bit_search_sentinel in bits.c.","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-2020-6613","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:libredwg","products":["gnu:libredwg","opensuse:backports_sle","opensuse:leap"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-6614"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-6612"},"products":["n/a"],"published":"2020-01-08","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-35164","kev_date_added":null,"published":"2022-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-28237","kev_date_added":null,"published":"2021-12-02"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2019-20914","kev_date_added":null,"published":"2020-07-16"},{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2019-9774","kev_date_added":null,"published":"2019-03-14"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2019-9775","kev_date_added":null,"published":"2019-03-14"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-36271","kev_date_added":null,"published":"2023-06-23"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-36272","kev_date_added":null,"published":"2023-06-23"}],"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 heap-based buffer over-read in GNU LibreDWG allows attackers to cause denial of service or disclose sensitive memory contents via crafted DWG files.","url":"https://insights.sbomify.com/CVE-2020-6613/"}
