An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-9923 exists.\n\nAffected product: Opensuse Leap. 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-2019-9923/ (Markdown: https://insights.sbomify.com/CVE-2019-9923/index.md)","id":"CVE-2019-9923","markdown":"https://insights.sbomify.com/CVE-2019-9923/index.md","name":"CVE-2019-9923","record":{"aliases":["CLSA-2025-1761744879","CLSA-2026-1777043727","CLSA-2026-1777049076","CLSA-2026-1777563191","CLSA-2026-1777564129","DEBIAN-CVE-2019-9923","GHSA-mg5f-88x3-g9cw","MGASA-2019-0164","UBUNTU-CVE-2019-9923"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GNU Tar utility","requires_auth":"none","summary":"A NULL pointer dereference in GNU Tar allows attackers to cause a denial of service via malformed extended headers in archives.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tar","vendor":"gnu"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"pax_decode_header in sparse.c in GNU Tar before 1.32 had a NULL pointer dereference when parsing certain archives that have malformed extended headers.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Null dereference in n/a","id":"CVE-2019-9923","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"opensuse:leap","products":["opensuse:leap"],"type":"null_dereference","year":"2019"},"n_packages":0,"n_references":6,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2019-9924"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2019-9922"},"products":["n/a"],"published":"2019-03-22","related":[{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2005-2541","kev_date_added":null,"published":"2005-08-10"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2016-6321","kev_date_added":null,"published":"2016-12-09"},{"cvss_score":6.8,"headline":"Path traversal in n/a","id":"CVE-2007-4131","kev_date_added":null,"published":"2007-08-25"},{"cvss_score":6.2,"headline":"Denial of service in n/a","id":"CVE-2023-39804","kev_date_added":null,"published":"2024-03-27"},{"cvss_score":5.1,"headline":"Memory corruption in n/a","id":"CVE-2006-0300","kev_date_added":null,"published":"2006-02-24"},{"cvss_score":5,"headline":"Tar: tar: hidden file injection via crafted archives","id":"CVE-2026-5704","kev_date_added":null,"published":"2026-04-06"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["n/a"]},"summary":"A NULL pointer dereference in GNU Tar allows attackers to cause a denial of service via malformed extended headers in archives.","url":"https://insights.sbomify.com/CVE-2019-9923/"}
