- Summary
- Heap buffer overflow due to incorrect hash function in TensorFlow
- Details
-
Impact
The
TensorKeyhash function used total estimatedAllocatedBytes(), which (a) is an estimate per tensor, and (b) is a very poor hash function for constants (e.g.int32_t). It also tried to access individual tensor bytes throughtensor.data()of sizeAllocatedBytes(). This led to ASAN failures because theAllocatedBytes()is an estimate of total bytes allocated by a tensor, including any pointed-to constructs (e.g. strings), and does not refer to contiguous bytes in the.data()buffer. We couldn't use this byte vector anyways, since types liketstringinclude pointers, whereas we need to hash the string values themselves.Patches
We have patched the issue in GitHub commit 1b85a28d395dc91f4d22b5f9e1e9a22e92ccecd6.
The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, which is the only other affected version.
