SCA: security update for OpenEXR (GHSA-588r-cr5c-w6hf)

high Tenable Self-Hosted Container Security Plugin ID 440057

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. From 3.1.0 to before 3.2.7, 3.3.9, and 3.4.9,
internal_exr_undo_piz() advances the working wavelet pointer with signed 32-bit arithmetic. Because nx,
ny, and wcount are int, a crafted EXR file can make this product overflow and wrap. The next channel then
decodes from an incorrect address. The wavelet decode path operates in place, so this yields both out-of-
bounds reads and out-of-bounds writes. This vulnerability is fixed in 3.2.7, 3.3.9, and 3.4.9.
(CVE-2026-34588)

Solution

Update the OpenEXR library and its related packages to version 3.2.7 or later.
