CVE-2020-15198

Heap buffer overflow in Tensorflow

State: Published
Severity: 5.4 Medium
Published: Sep 25, 2020
Updated: Aug 4, 2024
Reserved: Jun 25, 2020

Description

In Tensorflow before version 2.3.1, the `SparseCountSparseOutput` implementation does not validate that the input arguments form a valid sparse tensor. In particular, there is no validation that the `indices` tensor has the same shape as the `values` one. The values in these tensors are always accessed in parallel. Thus, a shape mismatch can result in accesses outside the bounds of heap allocated buffers. The issue is patched in commit 3cbb917b4714766030b28eba9fb41bb97ce9ee02 and is released in TensorFlow version 2.3.1.
