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-2018-10184 in the wild and no public exploit code.\n\nAffected product: Redhat Enterprise Linux. 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-2018-10184/ (Markdown: https://insights.sbomify.com/CVE-2018-10184/index.md)","id":"CVE-2018-10184","markdown":"https://insights.sbomify.com/CVE-2018-10184/index.md","name":"CVE-2018-10184","record":{"aliases":["CVE-2018-1119","DEBIAN-CVE-2018-10184","GHSA-v27h-hh5q-3p4q","RHBA-2018:1566","RHSA-2018:1372"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"HAProxy load balancer","requires_auth":"none","summary":"A heap overflow in HAProxy's HTTP/2 frame handling allows remote attackers to cause a denial of service via crafted frames.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"haproxy","vendor":"haproxy"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"An issue was discovered in HAProxy before 1.8.8. The incoming H2 frame length was checked against the max_frame_size setting instead of being checked against the bufsize. The max_frame_size only applies to outgoing traffic and not to incoming, so if a large enough frame size is advertised in the SETTINGS frame, a wrapped frame will be defragmented into a temporary allocated buffer where the second fragment may overflow the heap by up to 16 kB. It is very unlikely that this can be exploited for code execution given that buffers are very short lived and their addresses not realistically predictable in production, but the likelihood of an immediate crash is absolutely certain.","ecosystems":["Red Hat:openshift:3.9::el7","Red Hat:rhel_software_collections:3::el7"],"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":"Memory corruption in n/a","id":"CVE-2018-10184","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"redhat:enterprise_linux","products":["redhat:enterprise_linux"],"type":"memory_corruption","year":"2018"},"n_packages":6,"n_references":3,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2018-10185"},"packages":[{"ecosystem":"Red Hat:openshift:3.9::el7","fixed":["0:1.8.8-1.el7"],"introduced":["0"],"last_affected":[],"package":"haproxy","purl":"pkg:rpm/redhat/haproxy","source":"RHBA-2018:1566"},{"ecosystem":"Red Hat:openshift:3.9::el7","fixed":["0:1.8.8-1.el7"],"introduced":["0"],"last_affected":[],"package":"haproxy-debuginfo","purl":"pkg:rpm/redhat/haproxy-debuginfo","source":"RHBA-2018:1566"},{"ecosystem":"Red Hat:openshift:3.9::el7","fixed":["0:1.8.8-1.el7"],"introduced":["0"],"last_affected":[],"package":"haproxy18","purl":"pkg:rpm/redhat/haproxy18","source":"RHBA-2018:1566"},{"ecosystem":"Red Hat:rhel_software_collections:3::el7","fixed":["0:1.8.4-2.el7"],"introduced":["0"],"last_affected":[],"package":"rh-haproxy18-haproxy","purl":"pkg:rpm/redhat/rh-haproxy18-haproxy","source":"RHSA-2018:1372"},{"ecosystem":"Red Hat:rhel_software_collections:3::el7","fixed":["0:1.8.4-2.el7"],"introduced":["0"],"last_affected":[],"package":"rh-haproxy18-haproxy-debuginfo","purl":"pkg:rpm/redhat/rh-haproxy18-haproxy-debuginfo","source":"RHSA-2018:1372"},{"ecosystem":"Red Hat:rhel_software_collections:3::el7","fixed":["0:1.8.4-2.el7"],"introduced":["0"],"last_affected":[],"package":"rh-haproxy18-haproxy-syspaths","purl":"pkg:rpm/redhat/rh-haproxy18-haproxy-syspaths","source":"RHSA-2018:1372"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-10183"},"products":["n/a"],"published":"2018-05-09","related":[{"cvss_score":9,"headline":"HAProxy - Integer Overflow in FCGI Demux Record Length Field","id":"CVE-2026-55203","kev_date_added":null,"published":"2026-06-18"},{"cvss_score":8.7,"headline":"HAProxy - NULL Pointer Dereference in hpack_dht_insert Function","id":"CVE-2026-55204","kev_date_added":null,"published":"2026-06-18"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-45539","kev_date_added":null,"published":"2023-11-28"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-45506","kev_date_added":null,"published":"2024-09-04"},{"cvss_score":7.5,"headline":"Information disclosure in HAProxy","id":"CVE-2023-0836","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":7.5,"headline":"Other in n/a","id":"CVE-2019-18277","kev_date_added":null,"published":"2019-10-23"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2019-14241","kev_date_added":null,"published":"2019-07-23"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHBA"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"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":"A heap overflow in HAProxy's HTTP/2 frame handling allows remote attackers to cause a denial of service via crafted frames.","url":"https://insights.sbomify.com/CVE-2018-10184/"}
