An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-34161 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nginx (Bitnami): affected from 1.25.0; fixed in 1.26.1\n- nginx-gateway (Bitnami): affected from 1.25.0; fixed in 1.26.1\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-2024-34161/ (Markdown: https://insights.sbomify.com/CVE-2024-34161/index.md)","id":"CVE-2024-34161","markdown":"https://insights.sbomify.com/CVE-2024-34161/index.md","name":"CVE-2024-34161","record":{"aliases":["BIT-nginx-2024-34161","BIT-nginx-gateway-2024-34161","DEBIAN-CVE-2024-34161"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"NGINX web server","requires_auth":"none","summary":"Attackers can leak previously freed memory from NGINX workers via crafted QUIC packets when HTTP/3 is enabled with large MTUs.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"nginx_open_source","vendor":"f5"},{"product":"nginx_plus","vendor":"f5"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"When NGINX Plus or NGINX OSS are configured to use the HTTP/3 QUIC module and the network infrastructure supports a Maximum Transmission Unit (MTU) of 4096 or greater without fragmentation, undisclosed QUIC packets can cause NGINX worker processes to leak previously freed memory.","ecosystems":["Bitnami"],"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":"NGINX HTTP/3 QUIC vulnerability","id":"CVE-2024-34161","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"use_after_free","year":"2024"},"n_packages":2,"n_references":4,"next":{"headline":"Information disclosure in Multiple MFPs (multifunction printers)","id":"CVE-2024-34162"},"packages":[{"ecosystem":"Bitnami","fixed":["1.26.1"],"introduced":["1.25.0"],"last_affected":[],"package":"nginx","purl":"pkg:bitnami/nginx","source":"BIT-nginx-2024-34161"},{"ecosystem":"Bitnami","fixed":["1.26.1"],"introduced":["1.25.0"],"last_affected":[],"package":"nginx-gateway","purl":"pkg:bitnami/nginx-gateway","source":"BIT-nginx-gateway-2024-34161"}],"prev":{"headline":"Stack exhaustion in Parse in go/build/constraint","id":"CVE-2024-34158"},"products":["NGINX Open Source","NGINX Plus"],"published":"2024-05-29","related":[{"cvss_score":8.8,"headline":"NGINX ngx_http_dav_module vulnerability","id":"CVE-2026-27654","kev_date_added":null,"published":"2026-03-24"},{"cvss_score":8.7,"headline":"NGINX ngx_mail_auth_http_module vulnerability","id":"CVE-2026-27651","kev_date_added":null,"published":"2026-03-24"},{"cvss_score":8.5,"headline":"NGINX ngx_http_mp4_module vulnerability","id":"CVE-2026-27784","kev_date_added":null,"published":"2026-03-24"},{"cvss_score":8.5,"headline":"NGINX ngx_http_mp4_module vulnerability","id":"CVE-2026-32647","kev_date_added":null,"published":"2026-03-24"},{"cvss_score":7.5,"headline":"NGINX HTTP/3 QUIC vulnerability","id":"CVE-2024-24989","kev_date_added":null,"published":"2024-02-14"},{"cvss_score":7.5,"headline":"NGINX HTTP/3 QUIC vulnerability","id":"CVE-2024-24990","kev_date_added":null,"published":"2024-02-14"},{"cvss_score":6.5,"headline":"NGINX HTTP/3 QUIC vulnerability","id":"CVE-2024-32760","kev_date_added":null,"published":"2024-05-29"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["F5"]},"summary":"Attackers can leak previously freed memory from NGINX workers via crafted QUIC packets when HTTP/3 is enabled with large MTUs.","url":"https://insights.sbomify.com/CVE-2024-34161/"}
