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-2013-4206 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-2013-4206/ (Markdown: https://insights.sbomify.com/CVE-2013-4206/index.md)","id":"CVE-2013-4206","markdown":"https://insights.sbomify.com/CVE-2013-4206/index.md","name":"CVE-2013-4206","record":{"aliases":["DEBIAN-CVE-2013-4206","GHSA-h3qw-gcpw-f6mg"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SSH client","requires_auth":"none","summary":"Remote SSH servers can crash PuTTY or potentially execute code via a crafted DSA signature due to a heap buffer underflow.","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":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Heap-based buffer underflow in the modmul function in sshbn.c in PuTTY before 0.63 allows remote SSH servers to cause a denial of service (crash) and possibly trigger memory corruption or code execution via a crafted DSA signature, which is not properly handled when performing certain bit-shifting operations during modular multiplication.","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-2013-4206","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2013"},"n_packages":0,"n_references":7,"next":{"headline":"Memory corruption in n/a","id":"CVE-2013-4207"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2013-4205"},"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":"Remote SSH servers can crash PuTTY or potentially execute code via a crafted DSA signature due to a heap buffer underflow.","url":"https://insights.sbomify.com/CVE-2013-4206/"}
