OpenEXR is a high dynamic-range (HDR) image file format originally developed by Industrial Light & Magic for use in computer imaging applications.
Security Fix(es):
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> totalsizes for attacker-controlled large counts across many parts, totalsizes[ptr] wraps modulo 2^32. overallsamplecount is then derived from wrapped totals and used in samples[channel].resize(overallsamplecount). Decode pointer setup/consumption proceeds with true sample counts, and write operations in core unpack (genericunpackdeep_pointers) overrun the undersized composite sample buffer. This vulnerability is fixed in v3.2.6, v3.3.8, and v3.4.6.(CVE-2026-27622)
