It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2016-4656 in the wild since at least 24 May 2022.\n\nAffected product: Apple Iphone Os. 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-2016-4656/ (Markdown: https://insights.sbomify.com/CVE-2016-4656/index.md)","id":"CVE-2016-4656","markdown":"https://insights.sbomify.com/CVE-2016-4656/index.md","name":"CVE-2016-4656","record":{"aliases":["GHSA-6x59-8x45-xrp8"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"iOS kernel","requires_auth":"none","summary":"Attackers can execute arbitrary code or cause denial of service via a crafted app due to memory corruption in the iOS kernel.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apple","cpe":[{"product":"iphone_os","vendor":"apple"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"The kernel in Apple iOS before 9.3.5 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2016-08-25","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2016-08-25","kind":"metasploit","ref":"exploit/apple_ios/browser/webkit_trident","stars":null,"title":"WebKit not_number defineProperties UAF"},{"date":"2018-06-05","kind":"exploitdb","ref":"44836","stars":null,"title":"WebKit - not_number defineProperties UAF (Metasploit)"}],"tier":"exploited"},"has_fix":null,"headline":"Apple iOS Memory Corruption","id":"CVE-2016-4656","indexable":true,"kev":{"dateAdded":"2022-05-24","dueDate":"2022-06-14","knownRansomwareCampaignUse":"Unknown","product":"iOS","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Apple","vulnerabilityName":"Apple iOS Memory Corruption Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"apple:iphone_os","products":["apple:iphone_os"],"type":"memory_corruption","year":"2016"},"n_packages":0,"n_references":6,"next":{"headline":"Apple iOS Webkit Memory Corruption","id":"CVE-2016-4657"},"packages":[],"prev":{"headline":"Apple iOS Information Disclosure","id":"CVE-2016-4655"},"products":["n/a"],"published":"2016-08-25","related":[{"cvss_score":8.8,"headline":"Apple iOS WebKit Buffer Overflow","id":"CVE-2021-30666","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":8.8,"headline":"Apple iOS WebKit Memory Corruption","id":"CVE-2021-30761","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":8.8,"headline":"Apple iOS WebKit Use-After-Free","id":"CVE-2021-30762","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":8.8,"headline":"Apple iOS Webkit Memory Corruption","id":"CVE-2016-4657","kev_date_added":"2022-05-24","published":"2016-08-25"},{"cvss_score":7.8,"headline":"Apple Multiple Products Memory Corruption","id":"CVE-2019-7286","kev_date_added":"2022-05-23","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple iOS Memory Corruption","id":"CVE-2019-7287","kev_date_added":"2022-05-23","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple Multiple Products Use-After-Free","id":"CVE-2019-8605","kev_date_added":"2022-06-27","published":"2019-12-18"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code or cause denial of service via a crafted app due to memory corruption in the iOS kernel.","url":"https://insights.sbomify.com/CVE-2016-4656/"}
