GHSA-588R-CR5C-W6HF OpenEXR has a signed 32-bit Overflow in PIZ Decoder Leads to OOB Read/Write

Summary internalexrundopiz advances the working wavelet pointer with signed 32-bit arithmetic: c wavbuf += nx ny wcount; Because nx, ny, and wcount are int, a crafted EXR file can make this product overflow and wrap. The next channel then decodes from an incorrect address. The wavelet decode path...
