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-2017-2897 in the wild and no public exploit code.\n\nAffected product: libxls. 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-2017-2897/ (Markdown: https://insights.sbomify.com/CVE-2017-2897/index.md)","id":"CVE-2017-2897","markdown":"https://insights.sbomify.com/CVE-2017-2897/index.md","name":"CVE-2017-2897","record":{"aliases":["DEBIAN-CVE-2017-2897","GHSA-8p96-2vj8-w389","UBUNTU-CVE-2017-2897"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"libxls library","requires_auth":"none","summary":"A specially crafted XLS file triggers an out-of-bounds write in libxls, allowing remote code execution.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"libxls","vendor":"libxls_project"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An exploitable out-of-bounds write vulnerability exists in the read_MSAT function of libxls 1.4.
