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-2006-4339 in the wild and no public exploit code.\n\nAffected product: Openssl Openssl. 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-2006-4339/ (Markdown: https://insights.sbomify.com/CVE-2006-4339/index.md)","id":"CVE-2006-4339","markdown":"https://insights.sbomify.com/CVE-2006-4339/index.md","name":"CVE-2006-4339","record":{"aliases":["DEBIAN-CVE-2006-4339","DSA-1173-1","DSA-1174-1","GHSA-cw9v-mmf8-gmmr"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenSSL cryptographic library","requires_auth":"none","summary":"Remote attackers can forge PKCS #1 v1.5 signatures when RSA keys use exponent 3, bypassing certificate verification in OpenSSL.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"openssl","vendor":"openssl"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:N/A:N","version":"2.0"},"cwes":[{"id":"CWE-310","name":null}],"description":"OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8 before 0.9.8c, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents OpenSSL from correctly verifying X.509 and other certificates that use PKCS #1.","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":"Weak cryptography in n/a","id":"CVE-2006-4339","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openssl:openssl","products":["openssl:openssl"],"type":"weak_cryptography","year":"2006"},"n_packages":0,"n_references":209,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2006-4340"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2006-4338"},"products":["n/a"],"published":"2006-09-05","related":[{"cvss_score":10,"headline":"Null dereference in n/a","id":"CVE-2009-3245","kev_date_added":null,"published":"2010-03-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2006-3738","kev_date_added":null,"published":"2006-09-28"},{"cvss_score":9.8,"headline":"Untrusted Sender DN Used as Format String in CMP Response Validation","id":"CVE-2026-63073","kev_date_added":null,"published":"2026-08-25"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2016-6309","kev_date_added":null,"published":"2016-09-26"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2016-0799","kev_date_added":null,"published":"2016-03-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-2842","kev_date_added":null,"published":"2016-03-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2003-0545","kev_date_added":null,"published":"2003-10-01"}],"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 forge PKCS #1 v1.5 signatures when RSA keys use exponent 3, bypassing certificate verification in OpenSSL.","url":"https://insights.sbomify.com/CVE-2006-4339/"}
