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-2011-2940 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-2011-2940/ (Markdown: https://insights.sbomify.com/CVE-2011-2940/index.md)","id":"CVE-2011-2940","markdown":"https://insights.sbomify.com/CVE-2011-2940/index.md","name":"CVE-2011-2940","record":{"aliases":["DEBIAN-CVE-2011-2940","GHSA-rww2-jw3v-q88c"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SSL/TLS tunneling software","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause denial of service via heap memory corruption in stunnel.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"stunnel","vendor":"stunnel"}],"cvss":{"score":9.3,"severity":"critical","source":"nvd","vector":"AV:N/AC:M/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"stunnel 4.40 and 4.41 might allow remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.","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-2011-2940","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2011"},"n_packages":0,"n_references":10,"next":{"headline":"Open redirect in n/a","id":"CVE-2011-2941"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-2939"},"products":["n/a"],"published":"2011-08-25","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2001-0060","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":7.5,"headline":"Auth bypass in stunnel","id":"CVE-2021-20230","kev_date_added":null,"published":"2021-02-23"},{"cvss_score":7.2,"headline":"Unspecified vulnerability in stunnel before 4.23, when running as a service on Windows, allows local users to gain privileges via unknown attack vectors.","id":"CVE-2008-2400","kev_date_added":null,"published":"2008-05-22"},{"cvss_score":6.8,"headline":"Security feature bypass in n/a","id":"CVE-2008-2420","kev_date_added":null,"published":"2008-05-23"},{"cvss_score":6.6,"headline":"Integer overflow in n/a","id":"CVE-2013-1762","kev_date_added":null,"published":"2013-03-08"},{"cvss_score":5.8,"headline":"Auth bypass in n/a","id":"CVE-2015-3644","kev_date_added":null,"published":"2015-05-14"}],"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 attackers can execute arbitrary code or cause denial of service via heap memory corruption in stunnel.","url":"https://insights.sbomify.com/CVE-2011-2940/"}
