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-2018-20034 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-2018-20034/ (Markdown: https://insights.sbomify.com/CVE-2018-20034/index.md)","id":"CVE-2018-20034","markdown":"https://insights.sbomify.com/CVE-2018-20034/index.md","name":"CVE-2018-20034","record":{"aliases":["GHSA-fpjc-qw47-295v"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FlexNet Publisher","requires_auth":"none","summary":"Remote attackers can cause a denial of service in FlexNet Publisher by disrupting the heartbeat between lmgrd and the vendor daemon.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"flexera","cpe":[{"product":"flexnet_publisher","vendor":"flexera"},{"product":"communications_lsms","vendor":"oracle"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"A Denial of Service vulnerability related to adding an item to a list in lmgrd and vendor daemon components of FlexNet Publisher version 11.16.1.0 and earlier allows a remote attacker to send a combination of messages to lmgrd or the vendor daemon, causing the heartbeat between lmgrd and the vendor daemon to stop, and the vendor daemon to shut down.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in FlexNet Publisher","id":"CVE-2018-20034","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-20050"},"packages":[],"prev":{"headline":"Memory corruption in FlexNet Publisher","id":"CVE-2018-20033"},"products":["FlexNet Publisher"],"published":"2019-03-21","related":[{"cvss_score":9.8,"headline":"Memory corruption in FlexNet Publisher","id":"CVE-2018-20033","kev_date_added":null,"published":"2019-02-25"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2019-8963","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2020-12080","kev_date_added":null,"published":"2021-09-17"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2020-12081","kev_date_added":null,"published":"2020-07-31"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2019-8960","kev_date_added":null,"published":"2020-04-21"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2019-8961","kev_date_added":null,"published":"2020-04-21"},{"cvss_score":7.5,"headline":"Denial of service in FlexNet Publisher","id":"CVE-2018-20031","kev_date_added":null,"published":"2019-03-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Flexera Software LLC"]},"summary":"Remote attackers can cause a denial of service in FlexNet Publisher by disrupting the heartbeat between lmgrd and the vendor daemon.","url":"https://insights.sbomify.com/CVE-2018-20034/"}
