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."}, {"lang": "es", "value": "OpenEXR es la implementaci\u00f3n de referencia y la especificaci\u00f3n para el formato de imagen EXR, ampliamente utilizado en la industria cinematogr\u00e1fica.
