CVE-2021-37685

Advisory

Tensorflow-rocm 2.3.4, 2.4.3, 2.5.1 and 2.6.0 include a fix for CVE-2021-37685: In affected versions TFLite's 'expand_dims.cc' (https://github.com/tensorflow/tensorflow/blob/149562d49faa709ea80df1d99fc41d005b81082a/tensorflow/lite/kernels/expand_dims.cc#L36-L50) contains a vulnerability which allows reading one element outside of bounds of heap allocated data. If 'axis' is a large negative value (e.g., '-100000'), then after the first 'if' it would still be negative. The check following the 'if' statement will pass and the 'for' loop would read one element before the start of 'input_dims.data' (when 'i = 0'). The Tensorflow team has patched the issue in GitHub commit d94ffe08a65400f898241c0374e9edc6fa8ed257.
