Vulnerability CVE-2022-23559
Published: 2022-02-04   Modified: 2022-02-05

Description:
Tensorflow is an Open Source Machine Learning Framework. An attacker can craft a TFLite model that would cause an integer overflow in embedding lookup operations. Both `embedding_size` and `lookup_size` are products of values provided by the user. Hence, a malicious user could trigger overflows in the multiplication. In certain scenarios, this can then result in heap OOB read/write. Users are advised to upgrade to a patched version.

Type:

CWE-190

 (Integer Overflow or Wraparound)
