Descriptions

Array index error in the t42_parse_sfnts function in type42/t42parse.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via negative size values for certain strings in FontType42 font files, leading to a heap-based buffer overflow.

Error de índice de array en la función t42_parse_sfnts en type42/t42parse.c de FreeType anterior a v2.4.2 permite a atacantes remotos causar una denegación de servicio (fallo de la aplicación) o posiblemente ejecutar código a su elección a través de valores de tamaño negativo para ciertas cadenas en ficheros de fuentes FontType42, llevando a desbordamientos de búfer basados en pila.
