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-2009-2479 exists.\n\nAffected product: Mozilla Firefox. 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-2009-2479/ (Markdown: https://insights.sbomify.com/CVE-2009-2479/index.md)","id":"CVE-2009-2479","markdown":"https://insights.sbomify.com/CVE-2009-2479/index.md","name":"CVE-2009-2479","record":{"aliases":["GHSA-7mgv-jg63-hvqh"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mozilla Firefox","requires_auth":"none","summary":"Remote attackers can crash Mozilla Firefox on Windows by sending a long Unicode string to the write method, causing a denial of service.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"firefox","vendor":"mozilla"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Mozilla Firefox 3.0.x, 3.5, and 3.5.1 on Windows allows remote attackers to cause a denial of service (uncaught exception and application crash) via a long Unicode string argument to the write method.
