Heap buffer overflow due to incorrect hash function in TensorFlow
Impact The TensorKey hash function used total estimated AllocatedBytes, which a is an estimate per tensor, and b is a very poor hash function for constants e.g. int32t. It also tried to access individual tensor bytes through tensor.data of size AllocatedBytes. This led to ASAN failures because th...
CVE-2022-29210
TensorFlow is an open source platform for machine learning. In version 2.8.0, the TensorKey hash function used total estimated AllocatedBytes, which a is an estimate per tensor, and b is a very poor hash function for constants e.g. int32t. It also tried to access individual tensor bytes through...
CVE-2022-29210
CVE-2022-29210 affects TensorFlow 2.8.0, where TensorKey's hash using AllocatedBytes() and tensor.data() can cause a heap-buffer/ASAN-related issue leading to a denial of service. The issue is patched in TensorFlow 2.9.0 and also back-ported to 2.8.1. IBM Watson Discovery bulletin and OSV entries...
