SCA: security update for OpenEXR (GHSA-cr4v-6jm6-4963)

high Tenable Self-Hosted Container Security Plugin ID 438253

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2026-27622)
