Impact
When RangeSize
receives values that do not fit into an int64_t
, it crashes.
auto size = (std::is_integral<T>::value
? ((Eigen::numext::abs(limit - start) +
Eigen::numext::abs(delta) - T(1)) /
Eigen::numext::abs(delta))
: (Eigen::numext::ceil(
Eigen::numext::abs((limit - start) / delta))));
// This check does not cover all cases.
if (size > std::numeric_limits<int64_t>::max()) {
return errors::InvalidArgument("Requires ((limit - start) / delta) <= ",
std::numeric_limits<int64_t>::max());
}
c->set_output(0, c->Vector(static_cast<int64_t>(size)));
return Status::OK();
}
Patches
We have patched the issue in GitHub commit 37e64539cd29fcfb814c4451152a60f5d107b0f0.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
