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-2011-2391 in the wild and no public exploit code.\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-2011-2391/ (Markdown: https://insights.sbomify.com/CVE-2011-2391/index.md)","id":"CVE-2011-2391","markdown":"https://insights.sbomify.com/CVE-2011-2391/index.md","name":"CVE-2011-2391","record":{"aliases":["GHSA-wcjw-xjfg-7pww"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"iOS kernel","requires_auth":"none","summary":"Remote attackers can cause a denial of service via crafted ICMPv6 packets in the iOS kernel, requiring an OS upgrade.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"iphone_os","vendor":"apple"},{"product":"itunes","vendor":"apple"},{"product":"mac_os_x","vendor":"apple"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"AV:A/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The IPv6 implementation in the kernel in Apple iOS before 7 allows remote attackers to cause a denial of service (CPU consumption) via crafted ICMPv6 packets.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2011-2391","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apple:iphone_os","products":["apple:iphone_os","apple:itunes","apple:mac_os_x"],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":15,"next":{"headline":"Denial of service in n/a","id":"CVE-2011-2393"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-2386"},"products":["n/a"],"published":"2013-09-19","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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via crafted ICMPv6 packets in the iOS kernel, requiring an OS upgrade.","url":"https://insights.sbomify.com/CVE-2011-2391/"}
