TL;DR

Affected versions of this package are vulnerable to memory corruption when decoding DWA-compressed EXR files. A signed 32-bit multiplication of channel width and height can overflow for crafted dimensions, producing a wrapped pointer that the decoder writes through, causing out-of-bounds writes.

You are affected if you are using a version that falls within the vulnerable range.
