CVE-2019-16778: Heap buffer overflow in `UnsortedSegmentSum` in TensorFlow
(updated )
A heap buffer overflow in UnsortedSegmentSum
can be produced when the Index
template argument is int32
. In this case data_size
and num_segments
fields are truncated from int64
to int32
and can produce negative numbers, resulting in accessing out of bounds heap memory.
This is unlikely to be exploitable and was detected and fixed internally. We are making the security advisory only to notify users that it is better to update to TensorFlow 1.15 or 2.0 or later as these versions already have this fixed.
