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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-47797 exists.\n\nAffected product: Leawo Prof. Media. 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-2021-47797/ (Markdown: https://insights.sbomify.com/CVE-2021-47797/index.md)","id":"CVE-2021-47797","markdown":"https://insights.sbomify.com/CVE-2021-47797/index.md","name":"CVE-2021-47797","record":{"aliases":["GHSA-vfw6-v9vr-jfg2"],"analysis":{"component_type":"desktop_application","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Media conversion software","requires_auth":"none","summary":"Attackers can crash Leawo Prof. Media by pasting an oversized payload into the activation keycode field, causing a denial of service.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Leawo Prof. Media 11.0.0.1 contains a denial of service vulnerability that allows attackers to crash the application by supplying an oversized payload in the activation keycode field.
