DescriptionCVE.org

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. Versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13 allow a crafted EXR with a nonzero dataWindow.min to make TypedFlatImageChannel::row() return an invalid heap pointer, causing out-of-bounds or use-after-free writes. This occurs when an application writes rows through FlatHalfChannel::row(). Affected consumers are tools, converters, render pipeline components, or image-processing services that accept untrusted EXR files and use FlatHalfChannel::row() on loaded images. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.

AnalysisAI

Out-of-bounds and use-after-free memory writes in OpenEXR's FlatImageChannel row() API expose rendering pipelines and image-processing services to denial-of-service and potential memory corruption when handling untrusted EXR files. Affected versions include all releases before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13; the flaw is triggered specifically when an application calls FlatHalfChannel::row() on an EXR image with a nonzero dataWindow.min value. …

Vulnerability AssessmentAI

Exploitation Exploitation requires all of the following: (1) the target application links against an affected OpenEXR version (before 3.2.11, 3.3.0-3.3.12, or 3.4.0-3.4.13); (2) the application uses the OpenEXRUtil library and specifically invokes the TypedFlatImageChannel::row() or FlatHalfChannel::row() code path when writing pixel rows - applications that read EXR files without using this particular API are not vulnerable; (3) the application processes EXR files sourced from an attacker-controlled or untrusted input (the crafted file must have a nonzero dataWindow.min, which is a legitimate value per the EXR specification and passes normal format validation); and (4) a user or automated pipeline component must trigger the processing of the crafted file (CVSS UI:R). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 score of 7.1 with vector AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H accurately characterizes a network-reachable vulnerability requiring no privileges but demanding that a user or automated pipeline component process the crafted file. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade to OpenEXR 3.2.11, 3.3.13, or 3.4.14, which contain the corrected row() pointer arithmetic replacing '_base' with the direct buffer pointer in all affected channel types. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Conduct inventory of all OpenEXR deployments across rendering platforms, graphics applications, and image-processing workflows; restrict processing of untrusted external EXR files to isolated sandbox environments. …
