SCA: security update for tensorflow, tensorflow-cpu, tensorflow-gpu (GHSA-8pmx-p244-g88h)

medium Tenable Cloud Security Plugin ID 412791

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - TensorFlow is an end-to-end open source platform for machine learning. The implementation of
 `tf.io.decode_raw` produces incorrect results and crashes the Python interpreter when combining
 `fixed_length` and wider datatypes. The implementation of the padded version(https://github.com/tensorflow
 /tensorflow/blob/1d8903e5b167ed0432077a3db6e462daf781d1fe/tensorflow/core/kernels/decode_padded_raw_op.cc)
 is buggy due to a confusion about pointer arithmetic rules. First, the code computes(https://github.com/te
 nsorflow/tensorflow/blob/1d8903e5b167ed0432077a3db6e462daf781d1fe/tensorflow/core/kernels/decode_padded_ra
 w_op.cc#L61) the width of each output element by dividing the `fixed_length` value to the size of the type
 argument. The `fixed_length` argument is also used to determine the size needed for the output tensor(http
 s://github.com/tensorflow/tensorflow/blob/1d8903e5b167ed0432077a3db6e462daf781d1fe/tensorflow/core/kernels
 /decode_padded_raw_op.cc#L63-L79). This is followed by reencoding code(https://github.com/tensorflow/tenso
 rflow/blob/1d8903e5b167ed0432077a3db6e462daf781d1fe/tensorflow/core/kernels/decode_padded_raw_op.cc#L85-
 L94). The erroneous code is the last line above: it is moving the `out_data` pointer by `fixed_length *
 sizeof(T)` bytes whereas it only copied at most `fixed_length` bytes from the input. This results in parts
 of the input not being decoded into the output. Furthermore, because the pointer advance is far wider than
 desired, this quickly leads to writing to outside the bounds of the backing data. This OOB write leads to
 interpreter crash in the reproducer mentioned here, but more severe attacks can be mounted too, given that
 this gadget allows writing to periodically placed locations in memory. The fix will be included in
 TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow
 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range. (CVE-2021-29614)
