		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for OpenEXR is now available for openEuler-22.03-LTS-SP4</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">OpenEXR is a high dynamic-range (HDR) image file format originally developed by Industrial Light &amp;amp; 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&lt;unsigned int&gt; 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.(CVE-2026-27622)</Note>
