Description Alexandros Toptsoglou 2019-12-17 09:05:05 UTC

CVE-2019-16778

In TensorFlow before 1.15, 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 in TensorFlow 1.15 and 2.0.
