An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-13494 in the wild and no public exploit code.\n\nAffected product: Pixar. 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-2020-13494/ (Markdown: https://insights.sbomify.com/CVE-2020-13494/index.md)","id":"CVE-2020-13494","markdown":"https://insights.sbomify.com/CVE-2020-13494/index.md","name":"CVE-2020-13494","record":{"aliases":["GHSA-j3x9-vvcx-3wc5"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Pixar OpenUSD library","requires_auth":"none","summary":"Heap overflow in Pixar OpenUSD allows information disclosure and mitigation bypass via crafted files, requiring user interaction to open the file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"openusd","vendor":"pixar"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A heap overflow vulnerability exists in the Pixar OpenUSD 20.05 parsing of compressed string tokens in binary USD files.
