CVE-2020-26267: Google Tensorflow

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Google Tensorflow: before 1.15.5 (fixed in 1.15.5); from 2.0.0, before 2.0.4 (fixed in 2.0.4); from 2.1.0, before 2.1.3 (fixed in 2.1.3); from 2.2.0, before 2.2.2 (fixed in 2.2.2); from 2.3.0, before 2.3.2 (fixed in 2.3.2)
