CVE-2020-26267 Information

Description

In affected versions of TensorFlow 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 is fixed in versions 1.15.5 2.0.4 2.1.3 2.2.2 2.3.2 and 2.4.0.
