Summary
OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. In versions 3.4.0 through 3.4.9, 3.3.0 through 3.3.9, and 3.2.0 through 3.2.7, `internal_dwa_compressor.h:1040` performs `chan->width * chan->bytes_per_element` in `int32` arithmetic without a `(size_t)` cast. This is the same overflow pattern fixed in other decoders by CVE-2026-34589/34588/34544, but this line was missed. Versions 3.4.10, 3.3.10, and 3.2.8 contain a fix that addresses `internal_dwa_compressor.h:1040`.
