Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the read_tensor function when parsing attacker-controlled NNEF tensor dimensions. An attacker can cause out-of-bounds reads and potential information disclosure or denial of service by supplying crafted tensor files that exploit unchecked arithmetic to create a tensor whose reported length far exceeds its allocated buffer.
