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-2016-3959 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- stdlib (Go): affected all versions; fixed in 1.5.4, 1.6.1\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-2016-3959/ (Markdown: https://insights.sbomify.com/CVE-2016-3959/index.md)","id":"CVE-2016-3959","markdown":"https://insights.sbomify.com/CVE-2016-3959/index.md","name":"CVE-2016-3959","record":{"aliases":["AZL-79052","AZL-98631","GHSA-w7w7-9368-hffm","GO-2022-0166","MGASA-2016-0207"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go standard library","requires_auth":"none","summary":"Remote attackers can cause a denial of service via infinite loop in Go's DSA verification when processing crafted public keys in HTTPS or SSH contexts.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"go","vendor":"golang"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The Verify function in crypto/dsa/dsa.go in Go before 1.5.4 and 1.6.x before 1.6.1 does not properly check parameters passed to the big integer library, which might allow remote attackers to cause a denial of service (infinite loop) via a crafted public key to a program that uses HTTPS client certificates or SSH server libraries.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":"2016-04-10","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2016-04-10T01:35:27Z","kind":"github_poc","ref":"https://github.com/alexmullins/dsa","stars":1,"title":"Analysis of CVE-2016-3959 and a Proof of Concept Attack Against a Go SSH Server.
