Hi,
The following vulnerability was published for openexr.
CVE-2025-48074[0]:
| OpenEXR provides the specification and reference implementation of
| the EXR file format, an image storage format for the motion picture
| industry. In version 3.3.2, applications trust unvalidated
| dataWindow size values from file headers, which can lead to
| excessive memory allocation and performance degradation when
| processing malicious files. This is fixed in version 3.3.3.
While the advisory explicitly mentions only 3.3.2, by code inspection
I have not seen a reason why this should only ever have been
introduced in 3.3.2 and actually affect older versions (generally
anyway not trusting a CVE description as they reflect only e.g.
assessment in a given point in time).
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
