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.

OpenEXR, the reference implementation for the EXR image format widely used in the motion picture industry, contains a vulnerability in multiple versions. Affected versions include those before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13. The flaw resides in the TypedDeepImageChannel::row() function, which can return an out-of-bounds pointer when processing a crafted deep EXR file with a nonzero dataWindow origin. The root cause is an API design issue where zero-based row access is combined with an absolute-coordinate-adjusted base pointer. Exploitation of this vulnerability can lead to application crashes or limited information disclosure. Fixed versions are 3.2.11, 3.3.13, and 3.4.14. Multiple commits have been published to the OpenEXR GitHub repository addressing this issue. A GitHub Security Advisory (GHSA-6662-fq6f-93mp) has also been published.
