Descriptions
Leptonica before 1.75.3 does not limit the number of characters in a %s format argument to fscanf or sscanf, which allows remote attackers to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a long string, as demonstrated by the gplotRead and ptaReadStream functions.
Leptonica, en versiones anteriores a la 1.75.3, no limita el número de caracteres en un argumento de formato %s en fscanf o sscanf, lo que permite que atacantes remotos provoquen una denegación de servicio (desbordamiento de búfer basado en pila) o que puedan causar otro tipo de impacto sin especificar mediante una cadena larga. Esto se demuestra mediante las funciones gplotRead y ptaReadStream.
