      "value": "An issue was discovered in the DICOM Part 10 File Format in the NEMA DICOM Standard 1995 through 2019b. The preamble of a DICOM file that complies with this specification can contain the header for an executable file, such as Portable Executable (PE) malware. This space is left unspecified so that dual-purpose files can be created. (For example, dual-purpose TIFF/DICOM files are used in digital whole slide imaging for applications in medicine.) To exploit this vulnerability, someone must execute a maliciously crafted file that is encoded in the DICOM Part 10 File Format. PE/DICOM files are executable even with the .dcm file extension. Anti-malware configurations at healthcare facilities often ignore medical imagery. Also, anti-malware tools and business processes could violate regulatory frameworks (such as HIPAA) when processing suspicious DICOM files."

      "value": "Se detect\u00f3 un problema en el formato de archivo DICOM Part 10 en el estandar NEMA DICOM versi\u00f3n 1995 hasta 2019b. El pre\u00e1mbulo de un archivo DICOM que cumple con esta especificaci\u00f3n puede contener el encabezado de un archivo ejecutable, como lo es el malware Portable Executable (PE). Este espacio no se especifica para que se puedan crear archivos de doble prop\u00f3sito. (Por ejemplo, los archivos TIFF/DICOM de doble prop\u00f3sito se usan en im\u00e1genes de diapositivas digitales completas para aplicaciones en medicina). Para aprovechar esta vulnerabilidad, alguien debe ejecutar un archivo creado con fines maliciosos que est\u00e9 codificado en el formato de archivo DICOM Part 10. Los archivos PE/DICOM son ejecutables incluso con la extensi\u00f3n de archivo.dcm. Las configuraciones anti-malware en las instalaciones de salud a menudo ignoran las im\u00e1genes m\u00e9dicas. Adem\u00e1s, las herramientas antimalware y los procesos comerciales podr\u00edan infringir los marcos regulatorios (como HIPAA) al procesar archivos DICOM sospechosos."
