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-2009-1956 in the wild and no public exploit code.\n\nAffected product: Apache Http Server. 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-2009-1956/ (Markdown: https://insights.sbomify.com/CVE-2009-1956/index.md)","id":"CVE-2009-1956","markdown":"https://insights.sbomify.com/CVE-2009-1956/index.md","name":"CVE-2009-1956","record":{"aliases":["DEBIAN-CVE-2009-1956","GHSA-4wj9-j34x-wjxp"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache APR-util library","requires_auth":"none","summary":"Remote attackers can cause application crashes or leak sensitive information via crafted input due to an off-by-one error in the APR-util library.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"apr-util","vendor":"apache"},{"product":"http_server","vendor":"apache"},{"product":"ubuntu_linux","vendor":"canonical"}],"cvss":{"score":6.4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Off-by-one error in the apr_brigade_vprintf function in Apache APR-util before 1.3.5 on big-endian platforms allows remote attackers to obtain sensitive information or cause a denial of service (application crash) via crafted input.","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":"Integer overflow in n/a","id":"CVE-2009-1956","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apache:http_server","products":["apache:http_server","canonical:ubuntu_linux"],"type":"integer_overflow","year":"2009"},"n_packages":0,"n_references":52,"next":{"headline":"Null dereference in n/a","id":"CVE-2009-1957"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2009-1955"},"products":["n/a"],"published":"2009-06-06","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2009-2412","kev_date_added":null,"published":"2009-08-06"},{"cvss_score":9.1,"headline":"Apache Portable Runtime Utility: apr-util XML stack recursion crash","id":"CVE-2026-32327","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":9.1,"headline":"Apache Portable Runtime Utility: SQL Injection in apr_dbd_oracle","id":"CVE-2026-34191","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":7.5,"headline":"Apache Portable Runtime Utility: apr_password_validate() vulnerable to timing attack","id":"CVE-2025-49506","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":7.5,"headline":"Apache Portable Runtime Utility: Heap buffer overflow in APR redis client","id":"CVE-2026-34501","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":7.5,"headline":"Apache Portable Runtime Utility: Heap buffer overflow in APR memcached client","id":"CVE-2026-34502","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2009-1955","kev_date_added":null,"published":"2009-06-06"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can cause application crashes or leak sensitive information via crafted input due to an off-by-one error in the APR-util library.","url":"https://insights.sbomify.com/CVE-2009-1956/"}
