It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2017-8843 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-2017-8843/ (Markdown: https://insights.sbomify.com/CVE-2017-8843/index.md)","id":"CVE-2017-8843","markdown":"https://insights.sbomify.com/CVE-2017-8843/index.md","name":"CVE-2017-8843","record":{"aliases":["DEBIAN-CVE-2017-8843","GHSA-52fx-69c2-5gh6","UBUNTU-CVE-2017-8843"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"lrzip compression library","requires_auth":"none","summary":"Remote attackers can cause a denial of service via a crafted archive due to a NULL pointer dereference in the lrzip library.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"long_range_zip","vendor":"long_range_zip_project"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"The join_pthread function in stream.c in liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted archive.","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":"Null dereference in n/a","id":"CVE-2017-8843","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2017"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2017-8844"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2017-8842"},"products":["n/a"],"published":"2017-05-08","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2018-10685","kev_date_added":null,"published":"2018-05-02"},{"cvss_score":7.8,"headline":"Use after free in n/a","id":"CVE-2021-33453","kev_date_added":null,"published":"2022-07-26"},{"cvss_score":5.5,"headline":"Memory corruption in n/a","id":"CVE-2023-39741","kev_date_added":null,"published":"2023-08-17"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2021-33451","kev_date_added":null,"published":"2022-07-26"},{"cvss_score":5.5,"headline":"Integer overflow in n/a","id":"CVE-2022-33067","kev_date_added":null,"published":"2022-06-22"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2019-10654","kev_date_added":null,"published":"2019-03-30"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2018-9058","kev_date_added":null,"published":"2018-03-27"}],"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":"Remote attackers can cause a denial of service via a crafted archive due to a NULL pointer dereference in the lrzip library.","url":"https://insights.sbomify.com/CVE-2017-8843/"}
