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-2018-20712 in the wild and no public exploit code.\n\nAffected product: Gnu Binutils. 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-2018-20712/ (Markdown: https://insights.sbomify.com/CVE-2018-20712/index.md)","id":"CVE-2018-20712","markdown":"https://insights.sbomify.com/CVE-2018-20712/index.md","name":"CVE-2018-20712","record":{"aliases":["ALPINE-CVE-2018-20712","CLEANSTART-2025-QJ02692","DEBIAN-CVE-2018-20712","ECHO-0160-9330-67cd","GHSA-cgr8-f44r-j4r5","ROOT-OS-DEBIAN-12-CVE-2018-20712","UBUNTU-CVE-2018-20712"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GNU Binutils library","requires_auth":"none","summary":"A heap-based buffer over-read in GNU libiberty allows attackers to cause a denial of service via crafted input to c++filt.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"binutils","vendor":"gnu"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A heap-based buffer over-read exists in the function d_expression_1 in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31.1.
