Safety vulnerability ID: 42444
The information on this page was manually curated by our Cybersecurity Intelligence Team.
Affected versions of Tensorflow allow tensors to have a large number of dimensions and each dimension can be as large as desired. However, the total number of elements in a tensor must fit within an 'int64_t'. If an overflow occurs, 'MultiplyWithoutOverflow' would return a negative result. In the majority of TensorFlow codebase this then results in a 'CHECK'-failure. Newer constructs exist which return a 'Status' instead of crashing the binary. This is a similar issue to CVE-2021-29584.
Latest version: 2.16.1
TensorFlow is an open source machine learning framework for everyone.
TensorFlow is an open source platform for machine learning. In affected versions TensorFlow allows tensor to have a large number of dimensions and each dimension can be as large as desired. However, the total number of elements in a tensor must fit within an `int64_t`. If an overflow occurs, `MultiplyWithoutOverflow` would return a negative result. In the majority of TensorFlow codebase this then results in a `CHECK`-failure. Newer constructs exist which return a `Status` instead of crashing the binary. This is similar to CVE-2021-29584. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range. See CVE-2021-41197.
