CVE-2021-29518 Session operations in eager mode lead to null pointer dereferences

TensorFlow is an end-to-end open source platform for machine learning. In eager mode default in TF 2.0 and later, session operations are invalid. However, users could still call the raw ops associated with them and trigger a null pointer dereference. The...

CVE-2021-29520

TensorFlow CVE-2021-29520 concerns a heap buffer overflow in Conv3DBackprop* due to missing validation that assumes input, filter_sizes, and out_backprop have identical shapes. Multiple sources (OSV entries and GHSA advisory) corroborate the issue and patch lineage. The vulnerability affects Conv...

CVE-2021-29523 CHECK-fail in AddManySparseToTensorsMap

TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a denial of service via a CHECK-fail in tf.rawops.AddManySparseToTensorsMap. This is because the...

CVE-2021-29585

TensorFlow/TFLite padding compute path has a division-by-zero in ComputeOutSize when stride is 0, enabling a potential denial-of-service scenario via crafted models. The issue affects padding logic in TF Lite; patches were applied in commit 49847ae and a fix is planned for TensorFlow 2.5.0 with c...

CVE-2021-29588

TensorFlow/TFLite issue: the TransposeConv operator in the TFLite backend is vulnerable to a division-by-zero when stride_h/stride_w can be 0, enabling a crafted model to trigger a fault. Root cause follows from the division calculations in optimized_ops.h, requiring callers to validate stride ar...

CVE-2021-29590 Heap OOB read in TFLite's implementation of `Minimum` or `Maximum`

TensorFlow is an end-to-end open source platform for machine learning. The implementations of the Minimum and Maximum TFLite operators can be used to read data outside of bounds of heap allocated objects, if any of the two input tensor arguments are empty. This is because the broadcasting...
