Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the update function when non-contiguous buffers are provided as input. An attacker can cause memory corruption or unintended behavior by supplying specially crafted non-contiguous buffers to APIs that accept Python buffers.
Note: This is only exploitable if the Python version is greater than 3.11.
