An attacker can cause a heap buffer overflow in…","summary":"CVE-2021-29537 affects TensorFlow's `QuantizedResizeBilinear` operation, which causes a heap buffer overflow when an attacker passes invalid quantization thresholds. The implementation assumes both arguments are always valid scalars and reads their numeric values directly, so malformed input reaches memory it should not.","solution":"The fix will be included in TensorFlow 2.5.0. The commit will also be cherry-picked to TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, which are also affected and still within the supported range.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2021-29537","publishedAt":"2021-05-15T00:15:12.307Z","cveId":"CVE-2021-29537","cweIds":["CWE-131","CWE-787"],"cvssScore":"2.5","cvssSeverity":"low","severity":"low","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["tensorflow@<
