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-2012-1876 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-2012-1876/ (Markdown: https://insights.sbomify.com/CVE-2012-1876/index.md)","id":"CVE-2012-1876","markdown":"https://insights.sbomify.com/CVE-2012-1876/index.md","name":"CVE-2012-1876","record":{"aliases":["CVE-2012-1544","GHSA-mj6r-fxqr-4c2f"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Internet Explorer","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a heap-based buffer overflow in Internet Explorer when accessing a nonexistent object, requiring user interaction.","user_interaction":"required","vuln_class":"memory_corruption"},"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-94","name":"Improper Control of Generation of Code"}],"description":"Microsoft Internet Explorer 6 through 9, and 10 Consumer Preview, does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by attempting to access a nonexistent object, leading to a heap-based buffer overflow, aka \"Col Element Remote Code Execution Vulnerability,\" as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012.","ecosystems":[],"exploits":{"exploitdb":5,"first_seen":"2012-06-12","github_poc":2,"max_poc_stars":0,"metasploit":1,"nuclei":0,"refs":[{"date":"2012-06-12","kind":"metasploit","ref":"exploit/windows/browser/ms12_037_ie_colspan","stars":null,"title":"MS12-037 Microsoft Internet Explorer Fixed Table Col Span Heap Overflow"},{"date":"2012-08-02","kind":"exploitdb","ref":"20174","stars":null,"title":"Microsoft Internet Explorer -
