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-2011-1996 exists.\n\nAffected product: Microsoft Internet Explorer. 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-2011-1996/ (Markdown: https://insights.sbomify.com/CVE-2011-1996/index.md)","id":"CVE-2011-1996","markdown":"https://insights.sbomify.com/CVE-2011-1996/index.md","name":"CVE-2011-1996","record":{"aliases":["GHSA-gwx3-q7h2-fw63"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Internet Explorer browser","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a use-after-free vulnerability in Internet Explorer, requiring user interaction to visit a malicious page.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"internet_explorer","vendor":"microsoft"}],"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":[],"description":"Microsoft Internet Explorer 6 through 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing a deleted object, aka \"Option Element Remote Code Execution Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2012-10-11","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2012-10-11","kind":"metasploit","ref":"exploit/windows/browser/ms11_081_option","stars":null,"title":"MS11-081 Microsoft Internet Explorer Option Element Use-After-Free"},{"date":"2013-01-10","kind":"exploitdb","ref":"24020","stars":null,"title":"Microsoft Internet Explorer - Option Element Use-After-Free (MS11-081) (Metasploit)"}],"tier":"weaponised"},"has_fix":null,"headline":"Use after free in n/a","id":"CVE-2011-1996","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:internet_explorer","products":["microsoft:internet_explorer"],"type":"use_after_free","year":"2011"},"n_packages":0,"n_references":2,"next":{"headline":"Use after free in n/a","id":"CVE-2011-1997"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-1995"},"products":["n/a"],"published":"2011-10-12","related":[{"cvss_score":9.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2014-1776","kev_date_added":"2022-01-28","published":"2014-04-27"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Remote Code Execution","id":"CVE-2021-27085","kev_date_added":"2021-11-03","published":"2021-03-11"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Remote Code Execution","id":"CVE-2017-0222","kev_date_added":"2022-02-25","published":"2017-05-12"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Privilege Escalation","id":"CVE-2017-0210","kev_date_added":"2022-05-24","published":"2017-04-12"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2017-0149","kev_date_added":"2022-05-24","published":"2017-03-17"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2015-2502","kev_date_added":"2022-04-13","published":"2015-08-19"},{"cvss_score":8.8,"headline":"Microsoft Internet Explorer Memory Corruption","id":"CVE-2015-2419","kev_date_added":"2022-03-28","published":"2015-07-14"}],"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":"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 a use-after-free vulnerability in Internet Explorer, requiring user interaction to visit a malicious page.","url":"https://insights.sbomify.com/CVE-2011-1996/"}
