Summary

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. OpenEXR versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13 can return an out-of-bounds pointer from TypedDeepImageChannel::row() when a crafted deep EXR has a nonzero dataWindow origin. This vulnerability occurs because the API combines zero-based row access with an absolute-coordinate-adjusted base pointer, allowing a crash or limited information disclosure. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.

Inferred packages

No advisory lists a package for this vulnerability yet. The CVE names these as products and links their GitHub repository, and the package registry names the same repository, so they are probably the affected packages. Low confidence: the versions are the CVE’s own for the product, and a stack check reports the package as unchecked when there are none.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of AcademySoftwareFoundation/openexr published their own advisory on GitHub. Reviewed sources take precedence over it.
