It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-6977 in the wild and no public exploit code.\n\nAffected product: Vmware Esxi. 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-2018-6977/ (Markdown: https://insights.sbomify.com/CVE-2018-6977/index.md)","id":"CVE-2018-6977","markdown":"https://insights.sbomify.com/CVE-2018-6977/index.md","name":"CVE-2018-6977","record":{"aliases":["GHSA-29m2-93j9-hrcp"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"VMware virtualization software","requires_auth":"low_privilege","summary":"A guest user can trigger an infinite loop in 3D rendering, causing the virtual machine and potentially the host to become unresponsive.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"esxi","vendor":"vmware"},{"product":"fusion","vendor":"vmware"},{"product":"workstation","vendor":"vmware"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"VMware ESXi (6.7, 6.5, 6.0), Workstation (15.x and 14.x) and Fusion (11.x and 10.x) contain a denial-of-service vulnerability due to an infinite loop in a 3D-rendering shader.
