ETK-2026-3184Zero's internal tracking ID, independent of the CVE number.
waiting for further signalsZero needs more public information before it can validate it.description
Affected OpenEXRCore releases can expose residual heap data in decoded pixels when they process a malformed DWA-compressed EXR file. An attacker needs to provide an EXR to a service that decodes it and makes the resulting pixel data available, such as an image preview or conversion service.
mitigation
Upgrade openexr to 3.3.15, 3.4.17, 3.5.3 or later.
fixed in 3.3.15, 3.4.17, 3.5.3
outcome
Contextual, not validated: no deterministic check could cover this one, and no technique passed our review.
