GHSA-WVJW-P9F5-VQ28 Segfault in `tf.raw_ops.SparseCountSparseOutput`
Impact Passing invalid arguments e.g., discovered via fuzzing to tf.rawops.SparseCountSparseOutput results in segfault. Patches We have patched the issue in GitHub commit 82e6203221865de4008445b13c69b6826d2b28d9. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on...
GHSA-XQFJ-CR6Q-PC8W Crash in `tf.transpose` with complex inputs
Impact Passing a complex argument to tf.transpose at the same time as passing conjugate=True argument results in a crash: python import tensorflow as tf tf.transposeconjugate=True, a=complex1 Patches We have received a patch for the issue in GitHub commit 1dc6a7ce6e0b3e27a7ae650bfc05b195ca793f88...
GHSA-3QXP-QJQ7-W4HF CHECK-fail in tf.raw_ops.EncodePng
Impact An attacker can trigger a CHECK fail in PNG encoding by providing an empty input tensor as the pixel data: python import tensorflow as tf image = tf.zeros0, 0, 3 image = tf.castimage, dtype=tf.uint8 tf.rawops.EncodePngimage=image This is because the implementation only validates that the...
GHSA-HR84-FQVP-48MM Segfault in SparseCountSparseOutput
Impact Specifying a negative dense shape in tf.rawops.SparseCountSparseOutput results in a segmentation fault being thrown out from the standard library as std::vector invariants are broken. python import tensorflow as tf indices = tf.constant, shape=0, 0, dtype=tf.int64 values = tf.constant,...
