An attacker can trigger a denial of service via a `CHECK`-fail in converting sparse tensors to CSR Sparse matrices. This is because the implementation(https://github.com/tensorflow/tensorflow/blob/800346f2c03a27e182dd4fba48295f65e7790739/tensorflow/core/kernels/sparse/kernels.cc#L66) does a double redirection to access an element of an array allocated on the heap. If the value at `indices(i, 0)` is such that `indices(i, 0) + 1` is outside the bounds of `csr_row_ptr`, this results in writing outside of bounds of heap allocated data. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2021-29545","url":"https://www.suse.com/security/cve/CVE-2021-29545"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1186108 for CVE-2021-29545","url":"https://bugzilla.suse.com/1186108"}],"title":"SUSE CVE CVE-2021-29545","tracking":{"current_release_date":"2025-02-17T05:32:26Z","generator":{"date":"2023-02-15T03:43:17Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2021-29545","initial_release_date":"2023-02-15T03:43:17Z","revision_history":[{"date":"2023-02-15T03:43:17Z","number":"2","summary":"Current version"},{"date":"2025-01-01T04:35:16Z","number":"3","summary":"Current version"},{"date":"2025-02-15T05:09:38Z","number":"4","summary":"Current version"},{"date":"2025-02-17T05:32:26Z","number":"5","summary":"Current version"}],"status":"interim","version":"5"}}}
