AI-Generated

OpenEXR versions 3.1.0 through 3.2.10, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13 are vulnerable to an integer overflow in the unpack_sample_table() function, which can lead to a crash due to an invalid memory access when decoding specially crafted deep tiled EXR files. This vulnerability affects any application utilizing these versions for decoding EXR files, making it critical for developers and organizations in the motion picture industry to prioritize updating to the fixed versions 3.2.11, 3.3.13, or 3.4.14 to mitigate potential disruptions.

Original NVD Description

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.1.0 through 3.2.10, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13, an int32_t multiplication in OpenEXRCore's unpack_sample_table() can overflow while decoding a crafted deep tiled EXR file, producing an invalid pointer that leads to a read from an unmapped memory address and a crash. Because the overflow occurs in the standard decoding path (exr_decoding_run), any application that decodes deep tiled EXR files is affected. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.
