`std::abort` raised from `TensorListReserve`
Impact
Providing a negative element to num_elements list argument of tf.raw_ops.TensorListReserve causes the runtime to abort the process due to reallocating a std::vector to have a negative number of elements:
import tensorflow as tf
tf.raw_ops.TensorListReserve(
element_shape = tf.constant([1]),
num_elements=tf.constant([-1]),
element_dtype = tf.int32)The implementation calls std::vector.resize() with the new size controlled by input given by the user, without checking that this input is valid.
Patches
We have patched the issue in GitHub commit 8a6e874437670045e6c7dc6154c7412b4a2135e2.
The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.
