CVE-2022-23585: Memory leak in decoding PNG images
(updated )
When decoding PNG images TensorFlow can produce a memory leak if the image is invalid.
After calling png::CommonInitDecode(..., &decode), the decode value contains allocated buffers which can only be freed by calling png::CommonFreeDecode(&decode). However, several error case in the function implementation invoke the OP_REQUIRES macro which immediately terminates the execution of the function, without allowing for the memory free to occur.
