It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2015-1671 in the wild since at least 25 May 2022.\n\nAffected product: Microsoft .Net Framework. 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-2015-1671/ (Markdown: https://insights.sbomify.com/CVE-2015-1671/index.md)","id":"CVE-2015-1671","markdown":"https://insights.sbomify.com/CVE-2015-1671/index.md","name":"CVE-2015-1671","record":{"aliases":["GHSA-gr4p-px5x-x8jm"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows DirectWrite library","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a crafted TrueType font in the Windows DirectWrite library used by various Microsoft applications.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":".net_framework","vendor":"microsoft"},{"product":"live_meeting","vendor":"microsoft"},{"product":"lync","vendor":"microsoft"},{"product":"silverlight","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"The Windows DirectWrite library, as used in Microsoft .NET Framework 3.0 SP2, 3.5, 3.5.1, 4, 4.5, 4.5.1, and 4.5.2; Office 2007 SP3 and 2010 SP2; Live Meeting 2007 Console; Lync 2010; Lync 2010 Attendee; Lync 2013 SP1; Lync Basic 2013 SP1; Silverlight 5 before 5.1.40416.00; and Silverlight 5 Developer Runtime before 5.1.40416.00, allows remote attackers to execute arbitrary code via a crafted TrueType font, aka \"TrueType Font Parsing Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Windows Remote Code Execution","id":"CVE-2015-1671","indexable":true,"kev":{"dateAdded":"2022-05-25","dueDate":"2022-06-15","knownRansomwareCampaignUse":"Unknown","product":"Windows","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Windows Remote Code Execution Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:.net_framework","products":["microsoft:.net_framework"],"type":"memory_corruption","year":"2015"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2015-1672"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2015-1670"},"products":["n/a"],"published":"2015-05-13","related":[{"cvss_score":9.8,"headline":"Microsoft .NET Framework Remote Code Execution","id":"CVE-2020-0646","kev_date_added":"2021-11-03","published":"2020-01-14"},{"cvss_score":7.8,"headline":"Microsoft .NET Framework Remote Code Execution","id":"CVE-2017-8759","kev_date_added":"2021-11-03","published":"2017-09-13"},{"cvss_score":7.5,"headline":"Microsoft .NET Framework Information Disclosure","id":"CVE-2024-29059","kev_date_added":"2025-02-04","published":"2024-03-22"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2014-4073","kev_date_added":null,"published":"2014-10-15"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2014-4121","kev_date_added":null,"published":"2014-10-15"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2014-1806","kev_date_added":null,"published":"2014-05-14"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via a crafted TrueType font in the Windows DirectWrite library used by various Microsoft applications.","url":"https://insights.sbomify.com/CVE-2015-1671/"}
