CVE-2018-7577
TensorFlow checkpoint meta file uses Google's snappy compression/decompression library. There is a memcpy-param-overlap issue in the version of snappy currently used by TensorFlow.
A maliciously crafted checkpoint meta file could cause TensorFlow to crash or read from other parts of its process memory.
TensorFlow 1.1.0, 1.2.0, 1.2.1, 1.3.0, 1.3.1, 1.4.0, 1.4.1, 1.5.0, 1.5.1, 1.6.0, 1.7.0
We have patched the vulnerability in GitHub commit dfa9921e by upgrading the version of the snappy library used by TensorFlow to v1.1.7.
If users are loading untrusted checkpoints in TensorFlow, we encourage users to apply the patch to upgrade snappy.
Additionally, we have released TensorFlow version 1.7.1 to mitigate this vulnerability.
