An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-8641 exists.\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-2019-8641/ (Markdown: https://insights.sbomify.com/CVE-2019-8641/index.md)","id":"CVE-2019-8641","markdown":"https://insights.sbomify.com/CVE-2019-8641/index.md","name":"CVE-2019-8641","record":{"aliases":["GHSA-27cj-jh44-8xw6"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apple OS","requires_auth":"none","summary":"An out-of-bounds read in Apple operating systems allows attackers to disclose memory or cause a crash.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apple","cpe":[{"product":"iphone_os","vendor":"apple"},{"product":"mac_os_x","vendor":"apple"},{"product":"tvos","vendor":"apple"},{"product":"watchos","vendor":"apple"}],"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-125","name":"Out-of-bounds Read"}],"description":"An out-of-bounds read was addressed with improved input validation.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2019-09-24","github_poc":1,"max_poc_stars":6,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-05-29T07:37:15Z","kind":"github_poc","ref":"https://github.com/chia33164/CVE-2019-8641-reproduction","stars":6,"title":"The reproduction code for CVE-2019-8641."},{"date":"2019-09-24","kind":"exploitdb","ref":"47415","stars":null,"title":"iMessage - Decoding NSSharedKeyDictionary Can Read Object Out of Bounds"},{"date":"2019-11-11","kind":"exploitdb","ref":"47608","stars":null,"title":"iMessage - Decoding NSSharedKeyDictionary can read ObjC Object at Attacker Controlled Address"}],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in iOS","id":"CVE-2019-8641","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apple:iphone_os","products":["apple:iphone_os","apple:mac_os_x","apple:tvos","apple:watchos"],"type":"memory_corruption","year":"2019"},"n_packages":0,"n_references":5,"next":{"headline":"Security feature bypass in macOS","id":"CVE-2019-8642"},"packages":[],"prev":{"headline":"Security feature bypass in macOS","id":"CVE-2019-8640"},"products":["iOS","macOS","watchOS"],"published":"2019-12-18","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":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Apple"]},"summary":"An out-of-bounds read in Apple operating systems allows attackers to disclose memory or cause a crash.","url":"https://insights.sbomify.com/CVE-2019-8641/"}
