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-2009-1755 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2009-1755/ (Markdown: https://insights.sbomify.com/CVE-2009-1755/index.md)","id":"CVE-2009-1755","markdown":"https://insights.sbomify.com/CVE-2009-1755/index.md","name":"CVE-2009-1755","record":{"aliases":["DEBIAN-CVE-2009-1755","DSA-1803-1","GHSA-hvfw-j69f-c8f3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"NSD DNS server","requires_auth":"none","summary":"Remote attackers can cause a crash or execute arbitrary code via a buffer overflow in the NSD DNS server.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nsd","vendor":"nlnetlabs"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Off-by-one error in the packet_read_query_section function in packet.c in nsd 3.2.1, and process_query_section in query.c in nsd 2.3.7, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors that trigger a buffer overflow.","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":"Memory corruption in n/a","id":"CVE-2009-1755","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2009"},"n_packages":0,"n_references":4,"next":{"headline":"Information disclosure in n/a","id":"CVE-2009-1756"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2009-1754"},"products":["n/a"],"published":"2009-05-22","related":[{"cvss_score":8.7,"headline":"Heap overflow and crash with crafted SVCB RR","id":"CVE-2026-12244","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":8.7,"headline":"Denial of DNS over TLS service by any DoT client","id":"CVE-2026-12245","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":8.2,"headline":"Wrong interpretation of ACL ranges","id":"CVE-2026-18664","kev_date_added":null,"published":"2026-08-26"},{"cvss_score":8.2,"headline":"Remote UDP DoS by sending multiple DNS Cookie options","id":"CVE-2026-19401","kev_date_added":null,"published":"2026-08-26"},{"cvss_score":8.2,"headline":"Bypass of BLOCKED ACL items on proxy protocol port over TCP or TLS","id":"CVE-2026-19538","kev_date_added":null,"published":"2026-08-26"},{"cvss_score":8.2,"headline":"Bypass of client certificate verification with transfer over TLS","id":"CVE-2026-12490","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2016-6173","kev_date_added":null,"published":"2017-02-09"}],"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":"2024-09-17","vendors":["n/a"]},"summary":"Remote attackers can cause a crash or execute arbitrary code via a buffer overflow in the NSD DNS server.","url":"https://insights.sbomify.com/CVE-2009-1755/"}
