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-2018-20033 in the wild and no public exploit code.\n\nAffected product: Flexera Software LLC FlexNet Publisher. 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-2018-20033/ (Markdown: https://insights.sbomify.com/CVE-2018-20033/index.md)","id":"CVE-2018-20033","markdown":"https://insights.sbomify.com/CVE-2018-20033/index.md","name":"CVE-2018-20033","record":{"aliases":["GHSA-3jq8-j7q6-f6m6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"License management software","requires_auth":"none","summary":"Remote attackers can corrupt memory in FlexNet Publisher daemons, causing service shutdown and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"flexera","cpe":[{"product":"flexnet_publisher","vendor":"flexera"},{"product":"communications_lsms","vendor":"oracle"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A Remote Code Execution vulnerability in lmgrd and vendor daemon components of FlexNet Publisher version 11.16.1.0 and earlier could allow a remote attacker to corrupt the memory by allocating / deallocating memory, loading lmgrd or the vendor daemon and causing the heartbeat between lmgrd and the vendor daemon to stop.
