Comment 1 Ben Beasley 2025-12-02 10:29:41 UTC
It’s unfortunate that neither https://www.cve.org/CVERecord?id=CVE-2025-64181 nor https://github.com/AcademySoftwareFoundation/openexr/security/advisories/GHSA-3h9h-qfvw-98hq points out the precise fix. Still, it’s basically https://github.com/AcademySoftwareFoundation/openexr/compare/v3.4.2..v3.4.3 that needs to be backported to fix this and related issues. Some, but not all, of the affected code appears to be present in OpenUSD. I will attempt to craft a patch backporting the relevant changes.
