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-2020-1976 in the wild and no public exploit code.\n\nAffected product: Palo Alto Networks GlobalProtect. 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-2020-1976/ (Markdown: https://insights.sbomify.com/CVE-2020-1976/index.md)","id":"CVE-2020-1976","markdown":"https://insights.sbomify.com/CVE-2020-1976/index.md","name":"CVE-2020-1976","record":{"aliases":["GHSA-9x5h-34f3-92qm"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GlobalProtect client","requires_auth":"low_privilege","summary":"Authenticated local users can cause the Mac OS kernel to hang or crash via the GlobalProtect client, requiring an upgrade to remediate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"palo_alto","cpe":[{"product":"globalprotect","vendor":"paloaltonetworks"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-642","name":"External Control of Critical State Data"}],"description":"A denial-of-service (DoS) vulnerability in Palo Alto Networks GlobalProtect software running on Mac OS allows authenticated local users to cause the Mac OS kernel to hang or crash.
