An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-41159 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2021-41159/ (Markdown: https://insights.sbomify.com/CVE-2021-41159/index.md)","id":"CVE-2021-41159","markdown":"https://insights.sbomify.com/CVE-2021-41159/index.md","name":"CVE-2021-41159","record":{"aliases":["CLEANSTART-2024-VN48963","CLSA-2024-1723224273","DEBIAN-CVE-2021-41159","GHSA-vh34-m9h7-95xq","OESA-2021-1414","UBUNTU-CVE-2021-41159"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"RDP client library","requires_auth":"high_privilege","summary":"A malicious RDP gateway can trigger out-of-bounds memory writes in FreeRDP clients using RPC gateway connections, potentially allowing code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"freerdp","vendor":"freerdp"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
