1) Integer overflow (CVE-ID: CVE-2026-34380)
The vulnerability allows a remote attacker to cause a denial of service and modify memory.
The vulnerability exists due to integer overflow or wraparound in undo_pxr24_impl() in src/lib/OpenEXRCore/internal_pxr24.c when parsing a crafted PXR24-compressed EXR file. A remote attacker can supply a specially crafted EXR file to cause a denial of service and modify memory.
User interaction is required to open or process the crafted file, and exploitation requires a FLOAT channel using PXR24 compression.
