Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-15197 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tensorflow (Bitnami): affected from 2.3.0; fixed in 2.3.1\n- tensorflow (PyPI): affected all versions; fixed in 2.3.1\n- tensorflow (PyPI): affected from 2.3.0; fixed in 2.3.1\n- tensorflow (PyPI): affected from 2.3.0; fixed in 2.3.1\n- tensorflow-cpu (PyPI): affected all versions; fixed in 2.3.1\n- tensorflow-cpu (PyPI): affected from 2.3.0; fixed in 2.3.1\n- tensorflow-cpu (PyPI): affected from 2.3.0; fixed in 2.3.1\n- tensorflow-gpu (PyPI): affected all versions; fixed in 2.3.1\n- tensorflow-gpu (PyPI): affected from 2.3.0; fixed in 2.3.1\n- tensorflow-gpu (PyPI): affected from 2.3.0; fixed in 2.3.1\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-2020-15197/ (Markdown: https://insights.sbomify.com/CVE-2020-15197/index.md)","id":"CVE-2020-15197","markdown":"https://insights.sbomify.com/CVE-2020-15197/index.md","name":"CVE-2020-15197","record":{"aliases":["BIT-tensorflow-2020-15197","GHSA-qc53-44cj-vfvx","PYSEC-2020-120","PYSEC-2020-277","PYSEC-2020-312"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"TensorFlow library","requires_auth":"low_privilege","summary":"Attackers can cause a crash in TensorFlow serving installations by providing invalid sparse tensor inputs, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"tensorflow","vendor":"google"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In Tensorflow before version 2.3.1, the `SparseCountSparseOutput` implementation does not validate that the input arguments form a valid sparse tensor. In particular, there is no validation that the `indices` tensor has rank 2. This tensor must be a matrix because code assumes its elements are accessed as elements of a matrix. However, malicious users can pass in tensors of different rank, resulting in a `CHECK` assertion failure and a crash. This can be used to cause denial of service in serving installations, if users are allowed to control the components of the input sparse tensor.
