CVE-2020-15190

Advisory

Tensorflow-rocm versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 include a fix for CVE-2020-15190: In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the "tf.raw_ops.Switch" operation takes as input a tensor and a boolean and outputs two tensors. Depending on the boolean value, one of the tensors is exactly the input tensor whereas the other one should be an empty tensor. However, the eager runtime traverses all tensors in the output. Since only one of the tensors is defined, the other one is "nullptr", hence we are binding a reference to "nullptr". This is undefined behavior and reported as an error if compiling with "-fsanitize=null". In this case, this results in a segmentation fault The issue was patched in commit da8558533d925694483d2c136a9220d6d49d843c
