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-2010-3971 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-2010-3971/ (Markdown: https://insights.sbomify.com/CVE-2010-3971/index.md)","id":"CVE-2010-3971","markdown":"https://insights.sbomify.com/CVE-2010-3971/index.md","name":"CVE-2010-3971","record":{"aliases":["GHSA-r6fx-qpgx-pg2w"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Internet Explorer","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or crash the browser via a crafted CSS self-referential import rule in Internet Explorer.","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":[{"id":"CWE-399","name":null}],"description":"Use-after-free vulnerability in the CSharedStyleSheet::Notify function in the Cascading Style Sheets (CSS) parser in mshtml.dll, as used in Microsoft Internet Explorer 6 through 8 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a self-referential @import rule in a stylesheet, aka \"CSS Memory Corruption Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":3,"first_seen":"2010-11-29","github_poc":1,"max_poc_stars":2,"metasploit":1,"nuclei":0,"refs":[{"date":"2013-08-07T15:49:14Z","kind":"github_poc","ref":"https://github.com/nektra/CVE-2010-3971-hotpatch","stars":2,"title":"Do you own security hotfix with Deviare hooking"},{"date":"2010-11-29","kind":"metasploit","ref":"exploit/windows/browser/ms11_003_ie_css_import","stars":null,"title":"MS11-003 Microsoft Internet Explorer CSS Recursive Import Use After Free"},{"date":"2010-12-08","kind":"exploitdb","ref":"15708","stars":null,"title":"Microsoft Internet Explorer 8 - CSS Parser Denial of Service"},{"date":"2010-12-15","kind":"exploitdb","ref":"15746","stars":null,"title":"Microsoft Internet Explorer 8 - CSS Parser"},{"date":"2011-02-08","kind":"exploitdb","ref":"16533","stars":null,"title":"Microsoft Internet Explorer - CSS Recursive Import Use-After-Free (MS11-003) (Metasploit)"}],"tier":"weaponised"},"has_fix":null,"headline":"Use after free in n/a","id":"CVE-2010-3971","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:internet_explorer","products":["microsoft:internet_explorer"],"type":"use_after_free","year":"2010"},"n_packages":0,"n_references":16,"next":{"headline":"Memory corruption in n/a","id":"CVE-2010-3972"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2010-3970"},"products":["n/a"],"published":"2010-12-22","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":"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"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code or crash the browser via a crafted CSS self-referential import rule in Internet Explorer.","url":"https://insights.sbomify.com/CVE-2010-3971/"}
