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-2013-4207 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-2013-4207/ (Markdown: https://insights.sbomify.com/CVE-2013-4207/index.md)","id":"CVE-2013-4207","markdown":"https://insights.sbomify.com/CVE-2013-4207/index.md","name":"CVE-2013-4207","record":{"aliases":["DEBIAN-CVE-2013-4207","GHSA-gqcg-rpgj-92fp"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SSH client","requires_auth":"none","summary":"A remote SSH server can crash the PuTTY client by sending a malformed DSA signature, causing a buffer overflow during modular inverse computation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"putty","vendor":"putty"},{"product":"putty","vendor":"simon_tatham"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer overflow in sshbn.c in PuTTY before 0.63 allows remote SSH servers to cause a denial of service (crash) via an invalid DSA signature that is not properly handled during computation of a modular inverse and triggers the overflow during a division by zero by the bignum functionality, a different vulnerability than CVE-2013-4206.","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-2013-4207","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2013"},"n_packages":0,"n_references":6,"next":{"headline":"Information disclosure in n/a","id":"CVE-2013-4208"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2013-4206"},"products":["n/a"],"published":"2013-08-19","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2004-1008","kev_date_added":null,"published":"2004-12-01"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2019-17067","kev_date_added":null,"published":"2019-10-01"},{"cvss_score":8.1,"headline":"Auth bypass in n/a","id":"CVE-2021-36367","kev_date_added":null,"published":"2021-07-09"},{"cvss_score":7.8,"headline":"Other in n/a","id":"CVE-2016-6167","kev_date_added":null,"published":"2017-01-30"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2021-33500","kev_date_added":null,"published":"2021-05-21"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2005-0467","kev_date_added":null,"published":"2005-02-21"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2004-1440","kev_date_added":null,"published":"2005-02-13"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"A remote SSH server can crash the PuTTY client by sending a malformed DSA signature, causing a buffer overflow during modular inverse computation.","url":"https://insights.sbomify.com/CVE-2013-4207/"}
