Impact

A malicious user can cause a use after free behavior when [decoding PNG images](https://github.com/tensorflow/tensorflow/blob/a1320ec1eac186da1d03f033109191f715b2b130/tensorflow/core/kernels/image/decode image op.cc#L339-L346):
cc
if (/* ... error conditions ... */) {
 png::CommonFreeDecode(&decode);
 OP REQUIRES(context, false,
       errors::InvalidArgument("PNG size too large for int: ",
                   decode.width, " by ", decode.height));
}  
After png::CommonFreeDecode(&decode) gets called, the values of decode.width and decode.height are in an unspecified state.

Patches
