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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-43167 exists.\n\nAffected product: Red Hat Enterprise Linux 6. 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-2024-43167/ (Markdown: https://insights.sbomify.com/CVE-2024-43167/index.md)","id":"CVE-2024-43167","markdown":"https://insights.sbomify.com/CVE-2024-43167/index.md","name":"CVE-2024-43167","record":{"aliases":["AZL-47771","AZL-47779","DEBIAN-CVE-2024-43167","GHSA-f34v-4q4f-pf5q","MGASA-2024-0293","SUSE-SU-2024:3074-1","SUSE-SU-2024:3111-1","UBUNTU-CVE-2024-43167","openSUSE-SU-2024:14270-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Unbound DNS library","requires_auth":"low_privilege","summary":"A null pointer dereference in the Unbound library allows attackers to cause a denial of service via specific API call sequences.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":2.8,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"DISPUTE NOTE: this issue does not pose a security risk as it (according to analysis by the original software developer, NLnet Labs) falls within the expected functionality and security controls of the application. Red Hat has made a claim that there is a security risk within Red Hat products. NLnet Labs has no further information about the claim, and suggests that affected Red Hat customers refer to available Red Hat documentation or support channels. ORIGINAL DESCRIPTION: A NULL pointer dereference flaw was found in the ub_ctx_set_fwd function in Unbound. This issue could allow an attacker who can invoke specific sequences of API calls to cause a segmentation fault. When certain API functions such as ub_ctx_set_fwd and ub_ctx_resolvconf are called in a particular order, the program attempts to read from a NULL pointer, leading to a crash. This issue can result in a denial of service by causing the application to terminate unexpectedly.","ecosystems":["SUSE:Linux Enterprise Micro 5.5","SUSE:Linux Enterprise Module for Basesystem 15 SP5","SUSE:Linux Enterprise Module for Basesystem 15 SP6","SUSE:Linux Enterprise Module for Package Hub 15 SP5","SUSE:Linux Enterprise Module for Package Hub 15 SP6","openSUSE:Leap 15.5","openSUSE:Leap 15.6","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Unbound: null pointer dereference in unbound","id":"CVE-2024-43167","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2024"},"n_packages":8,"n_references":4,"next":{"headline":"Unbound: heap-buffer-overflow in unbound","id":"CVE-2024-43168"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Micro 5.5","fixed":["1.20.0-150100.10.16.1"],"introduced":["0"],"last_affected":[],"package":"unbound","purl":"pkg:rpm/suse/unbound\u0026distro=SUSE%20Linux%20Enterprise%20Micro%205.5","source":"SUSE-SU-2024:3074-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Basesystem 15 SP5","fixed":["1.20.0-150100.10.16.1"],"introduced":["0"],"last_affected":[],"package":"unbound","purl":"pkg:rpm/suse/unbound\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Basesystem%2015%20SP5","source":"SUSE-SU-2024:3074-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Basesystem 15 SP6","fixed":["1.20.0-150600.23.6.1"],"introduced":["0"],"last_affected":[],"package":"unbound","purl":"pkg:rpm/suse/unbound\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Basesystem%2015%20SP6","source":"SUSE-SU-2024:3111-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Package Hub 15 SP5","fixed":["1.20.0-150100.10.16.1"],"introduced":["0"],"last_affected":[],"package":"unbound","purl":"pkg:rpm/suse/unbound\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Package%20Hub%2015%20SP5","source":"SUSE-SU-2024:3074-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Package Hub 15 SP6","fixed":["1.20.0-150600.23.6.1"],"introduced":["0"],"last_affected":[],"package":"unbound","purl":"pkg:rpm/suse/unbound\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Package%20Hub%2015%20SP6","source":"SUSE-SU-2024:3111-1"},{"ecosystem":"openSUSE:Leap 15.5","fixed":["1.20.0-150100.10.16.1"],"introduced":["0"],"last_affected":[],"package":"unbound","purl":"pkg:rpm/opensuse/unbound\u0026distro=openSUSE%20Leap%2015.5","source":"SUSE-SU-2024:3074-1"},{"ecosystem":"openSUSE:Leap 15.6","fixed":["1.20.0-150600.23.6.1"],"introduced":["0"],"last_affected":[],"package":"unbound","purl":"pkg:rpm/opensuse/unbound\u0026distro=openSUSE%20Leap%2015.6","source":"SUSE-SU-2024:3111-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.21.0-1.1"],"introduced":["0"],"last_affected":[],"package":"unbound","purl":"pkg:rpm/opensuse/unbound\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:14270-1"}],"prev":{"headline":"Apache DolphinScheduler Incorrect Default Permissions Vulnerability","id":"CVE-2024-43166"},"products":["Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat OpenShift Container Platform 4","Red Hat OpenStack Platform 16.2","Red Hat OpenStack Platform 17.1","Red Hat OpenStack Platform 18.0"],"published":"2024-08-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"SUSE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"2025-11-03","vendors":["Red Hat"]},"summary":"A null pointer dereference in the Unbound library allows attackers to cause a denial of service via specific API call sequences.","url":"https://insights.sbomify.com/CVE-2024-43167/"}
