Descriptions
Ruby before 2.4.2, 2.3.5, and 2.2.8 is vulnerable to a malicious format string which contains a precious specifier (*) with a huge minus value. Such situation can lead to a buffer overrun, resulting in a heap memory corruption or an information disclosure from the heap.
Ruby, en versiones anteriores a la 2.4.2, 2.3.5 y 2.2.8, es vulnerable a una cadena de formato maliciosa qe contiene un especificador (*) con un valor grande negativo. Esta situación puede provocar un desbordamiento de búfer, provocando una corrupción de la memoria dinámica (heap) o una fuga de información de dicha memoria dinámica.
A buffer underflow was found in ruby's sprintf function. An attacker, with ability to control its format string parameter, could send a specially crafted string that would disclose heap memory or crash the interpreter.
