Upgrade openimageio to version 3.1.13.1 or higher.
Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the QueryRGBBufferSizeInternal function when processing crafted DPX image files. An attacker can cause a heap-based out-of-bounds write by supplying a specially crafted DPX file that triggers an integer overflow, leading to allocation of an undersized heap buffer and subsequent heap corruption when image data is written into it. This can result in application crashes or potentially allow execution of arbitrary code through heap corruption.
