Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-14871 in the wild and no public exploit code.\n\nAffected product: Red Hat newlib. 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-2019-14871/ (Markdown: https://insights.sbomify.com/CVE-2019-14871/index.md)","id":"CVE-2019-14871","markdown":"https://insights.sbomify.com/CVE-2019-14871/index.md","name":"CVE-2019-14871","record":{"aliases":["DEBIAN-CVE-2019-14871","GHSA-2q4g-qm2f-cq2j","UBUNTU-CVE-2019-14871"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"newlib C library","requires_auth":"low_privilege","summary":"A null pointer dereference in newlib macros can cause a denial of service in production firmware builds due to unchecked memory allocation failures.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"newlib","vendor":"newlib_project"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"The REENT_CHECK macro (see newlib/libc/include/sys/reent.h) as used by REENT_CHECK_TM, REENT_CHECK_MISC, REENT_CHECK_MP and other newlib macros in versions prior to 3.3.0, does not check for memory allocation problems when the DEBUG flag is unset (as is the case in production firmware builds).","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 newlib","id":"CVE-2019-14871","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in newlib","id":"CVE-2019-14872"},"packages":[],"prev":{"headline":"Auth bypass in samba","id":"CVE-2019-14870"},"products":["newlib"],"published":"2020-03-18","related":[{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2024-30949","kev_date_added":null,"published":"2024-08-20"},{"cvss_score":6.5,"headline":"Null dereference in newlib","id":"CVE-2019-14872","kev_date_added":null,"published":"2020-03-19"},{"cvss_score":6.5,"headline":"Null dereference in newlib","id":"CVE-2019-14873","kev_date_added":null,"published":"2020-03-19"},{"cvss_score":6.5,"headline":"Null dereference in newlib","id":"CVE-2019-14874","kev_date_added":null,"published":"2020-03-19"},{"cvss_score":6.5,"headline":"Null dereference in newlib","id":"CVE-2019-14875","kev_date_added":null,"published":"2020-03-19"},{"cvss_score":6.5,"headline":"Null dereference in newlib","id":"CVE-2019-14876","kev_date_added":null,"published":"2020-03-19"},{"cvss_score":6.5,"headline":"Null dereference in newlib","id":"CVE-2019-14877","kev_date_added":null,"published":"2020-03-19"}],"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":["Red Hat"]},"summary":"A null pointer dereference in newlib macros can cause a denial of service in production firmware builds due to unchecked memory allocation failures.","url":"https://insights.sbomify.com/CVE-2019-14871/"}
