Hi, The following vulnerability was published for openexr. CVE-2026-27622[0]: | OpenEXR provides the specification and reference implementation of | the EXR file format, an image storage format for the motion picture | industry. In CompositeDeepScanLine::readPixels, per-pixel totals are | accumulated in vector<unsigned int> total_sizes for attacker- | controlled large counts across many parts, total_sizes[ptr] wraps | modulo 2^32. overall_sample_count is then derived from wrapped | totals and used in samples[channel].resize(overall_sample_count). | Decode pointer setup/consumption proceeds with true sample counts, | and write operations in core unpack (generic_unpack_deep_pointers) | overrun the undersized composite sample buffer. This vulnerability | is fixed in v3.2.6, v3.3.8, and v3.4.6. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
