Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow via undo_zip_impl function during a write operation when decompressing ZIPS-packed deep scan-line EXR files. An attacker can write arbitrary data to the heap and potentially execute code by supplying a specially crafted EXR file with a forged chunk header.
