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-2020-36177 in the wild and no public exploit code.\n\nAffected product: Wolfssl Wolfssl. 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-2020-36177/ (Markdown: https://insights.sbomify.com/CVE-2020-36177/index.md)","id":"CVE-2020-36177","markdown":"https://insights.sbomify.com/CVE-2020-36177/index.md","name":"CVE-2020-36177","record":{"aliases":["DEBIAN-CVE-2020-36177","GHSA-68gc-rmhh-c4gg","UBUNTU-CVE-2020-36177"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"wolfSSL cryptographic library","requires_auth":"none","summary":"An out-of-bounds write in wolfSSL's RSA PSS padding allows attackers to potentially execute code or cause denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wolfssl","vendor":"wolfssl"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"RsaPad_PSS in wolfcrypt/src/rsa.c in wolfSSL before 4.6.0 has an out-of-bounds write for certain relationships between key size and digest size.","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-2020-36177","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wolfssl:wolfssl","products":["wolfssl:wolfssl"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":5,"next":{"headline":"Command injection in n/a","id":"CVE-2020-36178"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2020-36176"},"products":["n/a"],"published":"2021-01-06","related":[{"cvss_score":10,"headline":"Buffer overread in domain name matching","id":"CVE-2024-5991","kev_date_added":null,"published":"2024-08-27"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2021-37155","kev_date_added":null,"published":"2021-07-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-2896","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-2897","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2014-2898","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-16748","kev_date_added":null,"published":"2019-09-24"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"An out-of-bounds write in wolfSSL's RSA PSS padding allows attackers to potentially execute code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2020-36177/"}
