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-2020-6016 in the wild and no public exploit code.\n\nAffected product: Game Networking Sockets. 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-2020-6016/ (Markdown: https://insights.sbomify.com/CVE-2020-6016/index.md)","id":"CVE-2020-6016","markdown":"https://insights.sbomify.com/CVE-2020-6016/index.md","name":"CVE-2020-6016","record":{"aliases":["GHSA-2rgm-7354-cfw6"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Game Networking Sockets","requires_auth":"none","summary":"A heap-based buffer underflow in Valve's Game Networking Sockets library allows remote attackers to potentially execute arbitrary code via crafted unreliable segments.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"checkpoint","cpe":[{"product":"game_networking_sockets","vendor":"valvesoftware"}],"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"},{"id":"CWE-590","name":"Free of Memory not on the Heap"}],"description":"Valve's Game Networking Sockets prior to version v1.2.0 improperly handles unreliable segments with negative offsets in function SNP_ReceiveUnreliableSegment(), leading to a Heap-Based Buffer Underflow and a free() of memory not from the heap, resulting in a memory corruption and probably even a remote code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Memory corruption in Game Networking Sockets","id":"CVE-2020-6016","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in Game Networking Sockets","id":"CVE-2020-6017"},"packages":[],"prev":{"headline":"Path traversal in Check Point Endpoint Security for Windows","id":"CVE-2020-6015"},"products":["Game Networking Sockets"],"published":"2020-11-18","related":[{"cvss_score":9.8,"headline":"Memory corruption in Game Networking Sockets","id":"CVE-2020-6017","kev_date_added":null,"published":"2020-12-03"},{"cvss_score":9.8,"headline":"Memory corruption in Game Networking Sockets","id":"CVE-2020-6018","kev_date_added":null,"published":"2020-12-02"},{"cvss_score":7.5,"headline":"Denial of service in Game Networking Sockets","id":"CVE-2020-6019","kev_date_added":null,"published":"2020-11-13"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A heap-based buffer underflow in Valve's Game Networking Sockets library allows remote attackers to potentially execute arbitrary code via crafted unreliable segments.","url":"https://insights.sbomify.com/CVE-2020-6016/"}
