SCA: security update for tensorflow, tensorflow-cpu, tensorflow-gpu (GHSA-h6jh-7gv5-28vg)

medium Tenable Self-Hosted Container Security Plugin ID 415526

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. In affected versions the
 implementation of `tf.raw_ops.StringNGrams` is vulnerable to an integer overflow issue caused by
 converting a signed integer value to an unsigned one and then allocating memory based on this value. The [
 implementation](https://github.com/tensorflow/tensorflow/blob/8d72537c6abf5a44103b57b9c2e22c14f5f49698/ten
 sorflow/core/kernels/string_ngrams_op.cc#L184) calls `reserve` on a `tstring` with a value that sometimes
 can be negative if user supplies negative `ngram_widths`. The `reserve` method calls `TF_TString_Reserve`
 which has an `unsigned long` argument for the size of the buffer. Hence, the implicit conversion
 transforms the negative value to a large integer. We have patched the issue in GitHub commit
 c283e542a3f422420cfdb332414543b62fc4e4a5. The fix will be included in TensorFlow 2.6.0. We will also
 cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also
 affected and still in supported range. (CVE-2021-37646)
