It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-37445 exists.\n\nAffected product: Tonybybell Gtkwave. 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-2023-37445/ (Markdown: https://insights.sbomify.com/CVE-2023-37445/index.md)","id":"CVE-2023-37445","markdown":"https://insights.sbomify.com/CVE-2023-37445/index.md","name":"CVE-2023-37445","record":{"aliases":["DEBIAN-CVE-2023-37445","GHSA-fjfp-5xx8-cgr2","UBUNTU-CVE-2023-37445"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GTKWave waveform viewer","requires_auth":"none","summary":"A specially crafted VCD file can trigger out-of-bounds write in GTKWave's vcd2vzt utility, leading to arbitrary code execution.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"gtkwave","vendor":"tonybybell"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Multiple out-of-bounds read vulnerabilities exist in the VCD var definition section functionality of GTKWave 3.3.115.
