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-2009-0790 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-2009-0790/ (Markdown: https://insights.sbomify.com/CVE-2009-0790/index.md)","id":"CVE-2009-0790","markdown":"https://insights.sbomify.com/CVE-2009-0790/index.md","name":"CVE-2009-0790","record":{"aliases":["DEBIAN-CVE-2009-0790","DSA-1759-1","GHSA-xf8f-c2h7-7qmc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IPsec IKE daemon","requires_auth":"none","summary":"Remote attackers can crash the IPsec IKE daemon via crafted Dead Peer Detection messages, causing a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"strongswan","vendor":"strongswan"},{"product":"openswan","vendor":"xelerance"}],"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-20","name":"Improper Input Validation"}],"description":"The pluto IKE daemon in Openswan and Strongswan IPsec 2.6 before 2.6.21 and 2.4 before 2.4.14, and Strongswan 4.2 before 4.2.14 and 2.8 before 2.8.9, allows remote attackers to cause a denial of service (daemon crash and restart) via a crafted (1) R_U_THERE or (2) R_U_THERE_ACK Dead Peer Detection (DPD) IPsec IKE Notification message that triggers a NULL pointer dereference related to inconsistent ISAKMP state and the lack of a phase2 state association in DPD.","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":"Null dereference in n/a","id":"CVE-2009-0790","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2009"},"n_packages":0,"n_references":17,"next":{"headline":"Integer overflow in n/a","id":"CVE-2009-0791"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2009-0789"},"products":["n/a"],"published":"2009-04-01","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-41913","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2023-26463","kev_date_added":null,"published":"2023-04-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2015-3991","kev_date_added":null,"published":"2017-09-07"},{"cvss_score":7.7,"headline":"Auth bypass in strongSwan","id":"CVE-2022-4967","kev_date_added":null,"published":"2024-05-13"},{"cvss_score":7.5,"headline":"Null dereference in strongSwan","id":"CVE-2026-78130","kev_date_added":null,"published":"2026-09-11"},{"cvss_score":7.5,"headline":"Denial of service in strongSwan","id":"CVE-2026-78132","kev_date_added":null,"published":"2026-09-11"},{"cvss_score":7.5,"headline":"Use after free in strongSwan","id":"CVE-2026-78133","kev_date_added":null,"published":"2026-09-11"}],"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 crash the IPsec IKE daemon via crafted Dead Peer Detection messages, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2009-0790/"}
