An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-42459 in the wild and no public exploit code.\n\nAffected product: eProsima Fast-DDS. 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-2023-42459/ (Markdown: https://insights.sbomify.com/CVE-2023-42459/index.md)","id":"CVE-2023-42459","markdown":"https://insights.sbomify.com/CVE-2023-42459/index.md","name":"CVE-2023-42459","record":{"aliases":["DEBIAN-CVE-2023-42459","DSA-5568-1","GHSA-gq8g-fj58-22gm","UBUNTU-CVE-2023-42459"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Fast-DDS C++ library","requires_auth":"none","summary":"Remote attackers can crash Fast-DDS processes or potentially execute code by sending malformed DATA submessages to discovery locators.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fast_dds","vendor":"eprosima"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-590","name":"Free of Memory not on the Heap"},{"id":"CWE-416","name":"Use After Free"},{"id":"CWE-415","name":"Double Free"}],"description":"Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). In affected versions specific DATA submessages can be sent to a discovery locator which may trigger a free error. This can remotely crash any Fast-DDS process.
