An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2011-3659 exists.\n\nAffected product: Mozilla Firefox. 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-2011-3659/ (Markdown: https://insights.sbomify.com/CVE-2011-3659/index.md)","id":"CVE-2011-3659","markdown":"https://insights.sbomify.com/CVE-2011-3659/index.md","name":"CVE-2011-3659","record":{"aliases":["GHSA-6j4m-9ghg-x3p4"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Mozilla Firefox","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via use-after-free in Firefox, Thunderbird, and SeaMonkey by triggering incorrect DOM attribute notifications.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"firefox","vendor":"mozilla"},{"product":"seamonkey","vendor":"mozilla"},{"product":"thunderbird","vendor":"mozilla"},{"product":"opensuse","vendor":"opensuse"},{"product":"linux_enterprise_desktop","vendor":"suse"},{"product":"linux_enterprise_server","vendor":"suse"},{"product":"linux_enterprise_software_development_kit","vendor":"suse"}],"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-416","name":"Use After Free"}],"description":"Use-after-free vulnerability in Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 might allow remote attackers to execute arbitrary code via vectors related to incorrect AttributeChildRemoved notifications that affect access to removed nsDOMAttribute child nodes.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-12-06","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2011-12-06","kind":"metasploit","ref":"exploit/windows/browser/mozilla_attribchildremoved","stars":null,"title":"Firefox 8/9 AttributeChildRemoved() Use-After-Free"},{"date":"2012-05-13","kind":"exploitdb","ref":"18870","stars":null,"title":"Mozilla Firefox 8/9 - 'AttributeChildRemoved()' Use-After-Free (Metasploit)"}],"tier":"weaponised"},"has_fix":true,"headline":"Use after free in n/a","id":"CVE-2011-3659","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mozilla:firefox","products":["mozilla:firefox","mozilla:seamonkey","mozilla:thunderbird","opensuse:opensuse","suse:linux_enterprise_desktop","suse:linux_enterprise_server","suse:linux_enterprise_software_development_kit"],"type":"use_after_free","year":"2011"},"n_packages":0,"n_references":7,"next":{"headline":"Memory corruption in n/a","id":"CVE-2011-3660"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-3658"},"products":["n/a"],"published":"2012-02-01","related":[{"cvss_score":10,"headline":"Mozilla Firefox and Thunderbird Sandbox Escape","id":"CVE-2019-11708","kev_date_added":"2022-05-23","published":"2019-07-23"},{"cvss_score":9.8,"headline":"Mozilla Multiple Products Remote Code Execution","id":"CVE-2010-3765","kev_date_added":"2025-10-06","published":"2010-10-27"},{"cvss_score":9.6,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2022-26486","kev_date_added":"2022-03-07","published":"2022-12-22"},{"cvss_score":8.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2022-26485","kev_date_added":"2022-03-07","published":"2022-12-22"},{"cvss_score":8.8,"headline":"Mozilla Firefox and Thunderbird Type Confusion","id":"CVE-2019-11707","kev_date_added":"2022-05-23","published":"2019-07-23"},{"cvss_score":8.1,"headline":"Mozilla Firefox And Thunderbird Use-After-Free","id":"CVE-2020-6819","kev_date_added":"2021-11-03","published":"2020-04-24"},{"cvss_score":8.1,"headline":"Mozilla Firefox And Thunderbird Use-After-Free","id":"CVE-2020-6820","kev_date_added":"2021-11-03","published":"2020-04-24"}],"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":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via use-after-free in Firefox, Thunderbird, and SeaMonkey by triggering incorrect DOM attribute notifications.","url":"https://insights.sbomify.com/CVE-2011-3659/"}
