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-2009-3877 in the wild and no public exploit code.\n\nAffected product: Sun Jdk. 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-2009-3877/ (Markdown: https://insights.sbomify.com/CVE-2009-3877/index.md)","id":"CVE-2009-3877","markdown":"https://insights.sbomify.com/CVE-2009-3877/index.md","name":"CVE-2009-3877","record":{"aliases":["GHSA-23vf-7h8p-j4qp"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java SE Runtime","requires_auth":"none","summary":"Remote attackers can cause denial of service via crafted HTTP headers exploiting ASN.1 parser flaws in Java SE.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jdk","vendor":"sun"},{"product":"jre","vendor":"sun"},{"product":"sdk","vendor":"sun"}],"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-399","name":null}],"description":"Unspecified vulnerability in Sun Java SE in JDK and JRE 5.0 before Update 22, JDK and JRE 6 before Update 17, SDK and JRE 1.3.x before 1.3.1_27, and SDK and JRE 1.4.x before 1.4.2_24 allows remote attackers to cause a denial of service (memory consumption) via crafted HTTP headers, which are not properly parsed by the ASN.1 DER input stream parser, aka Bug Id 6864911.","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":"Denial of service in n/a","id":"CVE-2009-3877","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"sun:jdk","products":["sun:jdk","sun:jre","sun:sdk"],"type":"denial_of_service","year":"2009"},"n_packages":0,"n_references":26,"next":{"headline":"Memory corruption in n/a","id":"CVE-2009-3878"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2009-3876"},"products":["n/a"],"published":"2009-11-05","related":[{"cvss_score":10,"headline":"Deserialization in n/a","id":"CVE-2011-3521","kev_date_added":null,"published":"2011-10-19"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2011-3548","kev_date_added":null,"published":"2011-10-19"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2011-3549","kev_date_added":null,"published":"2011-10-19"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2011-3554","kev_date_added":null,"published":"2011-10-19"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2011-0802","kev_date_added":null,"published":"2011-06-14"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2011-0814","kev_date_added":null,"published":"2011-06-14"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2011-0815","kev_date_added":null,"published":"2011-06-14"}],"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 denial of service via crafted HTTP headers exploiting ASN.1 parser flaws in Java SE.","url":"https://insights.sbomify.com/CVE-2009-3877/"}
