      "value": "The ucnv_UTF8FromUTF8 function in ucnv_u8.cpp in International Components for Unicode (ICU) for C/C++ through 60.1 mishandles ucnv_convertEx calls for UTF-8 to UTF-8 conversion, which allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted string, as demonstrated by ZNC."

      "value": "La funci\u00f3n ucnv_UTF8FromUTF8 en ucnv_u8.cpp en International Components for Unicode (ICU) para C/C++ hasta la versi\u00f3n 60.1 gestiona de manera incorrecta las llamadas ucnv_convertEx para la conversi\u00f3n UTF-8 a UTF-8. Esto permite que atacantes remotos provoquen una denegaci\u00f3n de servicio (desbordamiento de b\u00fafer basado en pila y cierre inesperado de la aplicaci\u00f3n) o, posiblemente, causen otro impacto sin especificar mediante una cadena manipulada, tal y como demuestra ZNC."
