AI-Generated

OpenEXR versions 3.3.0 to 3.3.12 and 3.4.0 to 3.4.13 are vulnerable to a heap out-of-bounds write due to improper handling of pixel conversion options in the exrmetrics tool, which can lead to potential exploitation when processing crafted EXR files. This vulnerability poses a significant risk to organizations in the motion picture industry that rely on OpenEXR for image processing, necessitating immediate updates to versions 3.3.13 or 3.4.14 to mitigate potential attacks. Users of affected versions should prioritize patching to safeguard their systems against this high-severity vulnerability.

Original NVD Description

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. OpenEXR versions 3.3.0 through 3.3.12 and 3.4.0 through 3.4.13 are vulnerable to a heap out-of-bounds write when exrmetrics reads a crafted deep scanline EXR. This occurs with pixel conversion options such as --pixelmode float or --bench because DeepSlice requests FLOAT output while the backing sample buffers are allocated using the input HALF element size. The issue is fixed in versions 3.3.13 and 3.4.14.
