Vulnerability CVE-2022-23593 - CERT Civis.Net

Vulnerability Name:

CVE-2022-23593 (CCN-218895)

Assigned:

2022-02-02

Published:

2022-02-02

Updated:

2022-02-10

Summary:

Tensorflow is an Open Source Machine Learning Framework. The `simplifyBroadcast` function in the MLIR-TFRT infrastructure in TensorFlow is vulnerable to a segfault (hence, denial of service), if called with scalar shapes. If all shapes are scalar, then `maxRank` is 0, so we build an empty `SmallVector`. The fix will be included in TensorFlow 2.8.0. This is the only affected version.
