Out-of-bounds Read

CVE-2020-26267

High
7.8/10

Summary

In TensorFlow before 1.15.5, 2.0.0 through 2.0.3, 2.1.0 through 2.1.2, 2.2.0 through 2.2.1, and 2.3.0 through 2.3.1, the tf.raw_ops.DataFormatVecPermute API does not validate the src_format and dst_format attributes. The code assumes that these two arguments define a permutation of NHWC. This can result in uninitialized memory accesses, read outside of bounds and even crashes. This also affects tensorflow-cpu and tensorflow-gpu packages. It's fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0.
