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-2016-4456 in the wild and no public exploit code.\n\nAffected product: Gnu Gnutls. 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-2016-4456/ (Markdown: https://insights.sbomify.com/CVE-2016-4456/index.md)","id":"CVE-2016-4456","markdown":"https://insights.sbomify.com/CVE-2016-4456/index.md","name":"CVE-2016-4456","record":{"aliases":["DEBIAN-CVE-2016-4456","GHSA-f425-wv72-9hrq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"GnuTLS library","requires_auth":"none","summary":"Remote attackers can overwrite arbitrary files via the GNUTLS_KEYLOGFILE environment variable, requiring specific configuration to exploit.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"gnutls","vendor":"gnu"}],"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:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The \"GNUTLS_KEYLOGFILE\" environment variable in gnutls 3.4.12 allows remote attackers to overwrite and corrupt arbitrary files in the filesystem.","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":"Path traversal in n/a","id":"CVE-2016-4456","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:gnutls","products":["gnu:gnutls"],"type":"path_traversal","year":"2016"},"n_packages":0,"n_references":2,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2016-4457"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2016-4455"},"products":["n/a"],"published":"2017-08-08","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-1948","kev_date_added":null,"published":"2008-05-21"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2017-5334","kev_date_added":null,"published":"2017-03-24"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-5336","kev_date_added":null,"published":"2017-03-24"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-5337","kev_date_added":null,"published":"2017-03-24"},{"cvss_score":9.3,"headline":"Null dereference in n/a","id":"CVE-2008-1949","kev_date_added":null,"published":"2008-05-21"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2004-2531","kev_date_added":null,"published":"2005-10-25"},{"cvss_score":7.6,"headline":"Use after free in n/a","id":"CVE-2008-2377","kev_date_added":null,"published":"2008-08-08"}],"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 overwrite arbitrary files via the GNUTLS_KEYLOGFILE environment variable, requiring specific configuration to exploit.","url":"https://insights.sbomify.com/CVE-2016-4456/"}
