It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-31979 exists.\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-2023-31979/ (Markdown: https://insights.sbomify.com/CVE-2023-31979/index.md)","id":"CVE-2023-31979","markdown":"https://insights.sbomify.com/CVE-2023-31979/index.md","name":"CVE-2023-31979","record":{"aliases":["DEBIAN-CVE-2023-31979","GHSA-3rq8-339r-782q","UBUNTU-CVE-2023-31979"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Catdoc file reader","requires_auth":"low_privilege","summary":"A global buffer overflow in Catdoc allows attackers to execute arbitrary code or cause denial of service via malicious files.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"catdoc","vendor":"fossies"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Catdoc v0.95 was discovered to contain a global buffer overflow via the function process_file at /src/reader.c.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Memory corruption in n/a","id":"CVE-2023-31979","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2023-31981"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-31976"},"products":["n/a"],"published":"2023-05-09","related":[{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2017-11110","kev_date_added":null,"published":"2017-07-08"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2023-46345","kev_date_added":null,"published":"2023-10-25"},{"cvss_score":5.5,"headline":"Null dereference in n/a","id":"CVE-2023-41633","kev_date_added":null,"published":"2023-09-01"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-01-29","vendors":["n/a"]},"summary":"A global buffer overflow in Catdoc allows attackers to execute arbitrary code or cause denial of service via malicious files.","url":"https://insights.sbomify.com/CVE-2023-31979/"}
