CVE-2021-37649 - log back

CVE-2021-37649 created at 13 Aug 2021 07:58:00
Severity	+ Low
Remote	+ Local
Type	+ Denial of service
Description	+ In TensorFlow before version 2.6.0, the code for tf.raw_ops.UncompressElement can be made to trigger a null pointer dereference. The implementation obtains a pointer to a CompressedElement from a Variant tensor and then proceeds to dereference it for decompressing. There is no check that the Variant tensor contained a CompressedElement, so the pointer is actually nullptr.
