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-2020-29652 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang.org/x/crypto (Go): affected all versions; fixed in 0.0.0-20201216223049-8b5274cf687f\n- golang.org/x/crypto (Go): affected all versions; fixed in 0.0.0-20201216223049-8b5274cf687f\n- golang.org/x/crypto (Go): affected all versions; fixed in 0.0.0-20201216223049-8b5274cf687f\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-2020-29652/ (Markdown: https://insights.sbomify.com/CVE-2020-29652/index.md)","id":"CVE-2020-29652","markdown":"https://insights.sbomify.com/CVE-2020-29652/index.md","name":"CVE-2020-29652","record":{"aliases":["CLEANSTART-2026-RN21890","CLEANSTART-2026-VL48294","DEBIAN-CVE-2020-29652","GHSA-3vm4-22fp-5rfm","GO-2021-0227","UBUNTU-CVE-2020-29652","openSUSE-SU-2024:11667-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go SSH library","requires_auth":"none","summary":"Remote attackers can cause a denial of service against SSH servers using the Go SSH library due to a nil pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ssh","vendor":"golang"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A nil pointer dereference in the golang.org/x/crypto/ssh component through v0.0.0-20201203163018-be400aefbc4c for Go allows remote attackers to cause a denial of service against SSH servers.","ecosystems":["Go","openSUSE:Tumbleweed"],"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":"golang.org/x/crypto/ssh NULL Pointer Dereference vulnerability","id":"CVE-2020-29652","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"null_dereference","year":"2020"},"n_packages":4,"n_references":3,"next":{"headline":"HTML Injection in Froxlor","id":"CVE-2020-29653"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20201216223049-8b5274cf687f"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/crypto","purl":null,"source":"GHSA-3vm4-22fp-5rfm"},{"ecosystem":"Go","fixed":["0.0.0-20201216223049-8b5274cf687f"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/crypto","purl":"pkg:golang/golang.org/x/crypto","source":"GHSA-3vm4-22fp-5rfm"},{"ecosystem":"Go","fixed":["0.0.0-20201216223049-8b5274cf687f"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/crypto","purl":"pkg:golang/golang.org/x/crypto","source":"GO-2021-0227"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.7.1-1.1"],"introduced":["0"],"last_affected":[],"package":"velero","purl":"pkg:rpm/opensuse/velero\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11667-1"}],"prev":{"headline":"py vulnerable to Regular Expression Denial of Service","id":"CVE-2020-29651"},"products":["n/a"],"published":"2020-12-17","related":[{"cvss_score":7.5,"headline":"x/crypto/ssh vulnerable to panic via malformed packets","id":"CVE-2021-43565","kev_date_added":null,"published":"2022-09-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"Remote attackers can cause a denial of service against SSH servers using the Go SSH library due to a nil pointer dereference.","url":"https://insights.sbomify.com/CVE-2020-29652/"}
