Descriptions
The (1) lc, (2) lcfirst, (3) uc, and (4) ucfirst functions in Perl 5.10.x, 5.11.x, and 5.12.x through 5.12.3, and 5.13.x through 5.13.11, do not apply the taint attribute to the return value upon processing tainted input, which might allow context-dependent attackers to bypass the taint protection mechanism via a crafted string.
Las funciones (1) lc, (2) lcfirst, (3) uc, y (4) ucfirst en Perl v5.10.x, v5.11.x, y v5.12.x hasta v5.12.3, y v5.13.x hasta v5.13.11, no aplica el atributo taint para devolver el valor sobre el proceso de entrada tainted, lo que puede permitir a atacantes dependientes del contexto evitar el mecanismo de protección de taint a través de una cadena manipulada.
