Descriptions

The resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C in International Components for Unicode (ICU) before 55.1 uses an integer data type that is inconsistent with a header file, which allows remote attackers to cause a denial of service (incorrect malloc followed by invalid free) or possibly execute arbitrary code via crafted text.

La función resolveImplicitLevels en common/ubidi.c en la implementación Unicode Bidirectional Algorithm en ICU4C en International Components for Unicode (ICU) anterior a 55.1 utiliza un tipo de datos de enteros que es inconsistente con un fichero de cabeceras, lo que permite a atacantes remotos causar una denegación de servicio (malloc incorrecto seguido por liberación inválida) o posiblemente ejecutar código arbitrario a través de texto manipulado.
