An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2011-1873 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 7. 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-2011-1873/ (Markdown: https://insights.sbomify.com/CVE-2011-1873/index.md)","id":"CVE-2011-1873","markdown":"https://insights.sbomify.com/CVE-2011-1873/index.md","name":"CVE-2011-1873","record":{"aliases":["GHSA-8pff-c9jf-g9ff"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows kernel driver","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Windows systems by tricking users into opening a crafted OpenType font file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_7","vendor":"microsoft"},{"product":"windows_server_2003","vendor":"microsoft"},{"product":"windows_server_2008","vendor":"microsoft"},{"product":"windows_vista","vendor":"microsoft"},{"product":"windows_xp","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-20","name":"Improper Input Validation"}],"description":"win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 on 64-bit platforms does not properly validate pointers during the parsing of OpenType (aka OTF) fonts, which allows remote attackers to execute arbitrary code via a crafted font file, aka \"Win32k OTF Validation Vulnerability.\"","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":"Memory corruption in n/a","id":"CVE-2011-1873","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_7","products":["microsoft:windows_7","microsoft:windows_server_2003","microsoft:windows_server_2008","microsoft:windows_vista","microsoft:windows_xp"],"type":"memory_corruption","year":"2011"},"n_packages":0,"n_references":6,"next":{"headline":"Use after free in n/a","id":"CVE-2011-1874"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2011-1872"},"products":["n/a"],"published":"2011-06-16","related":[{"cvss_score":9.8,"headline":"Microsoft HTTP.sys Remote Code Execution","id":"CVE-2015-1635","kev_date_added":"2022-02-10","published":"2015-04-14"},{"cvss_score":8.8,"headline":"Microsoft Win32k Privilege Escalation","id":"CVE-2015-2360","kev_date_added":"2022-05-25","published":"2015-06-10"},{"cvss_score":8.8,"headline":"Microsoft Kerberos Key Distribution Center (KDC) Privilege Escalation","id":"CVE-2014-6324","kev_date_added":"2022-03-25","published":"2014-11-18"},{"cvss_score":8.8,"headline":"Microsoft Windows Object Linking \u0026 Embedding (OLE) Automation Array Remote Code Execution","id":"CVE-2014-6332","kev_date_added":"2022-03-25","published":"2014-11-11"},{"cvss_score":8.8,"headline":"Microsoft Windows Remote Code Execution","id":"CVE-2014-4148","kev_date_added":"2022-05-25","published":"2014-10-15"},{"cvss_score":8.8,"headline":"Microsoft Windows Group Policy Preferences Password Privilege Escalation","id":"CVE-2014-1812","kev_date_added":"2021-11-03","published":"2014-05-14"},{"cvss_score":8.8,"headline":"Microsoft Windows Out-of-Bounds Write","id":"CVE-2013-3918","kev_date_added":"2025-10-06","published":"2013-11-12"}],"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 execute arbitrary code on Windows systems by tricking users into opening a crafted OpenType font file.","url":"https://insights.sbomify.com/CVE-2011-1873/"}
