Descriptions

The safe-level feature in Ruby 1.8.6 through 1.8.6-420, 1.8.7 through 1.8.7-330, and 1.8.8dev allows context-dependent attackers to modify strings via the Exception#to_s method, as demonstrated by changing an intended pathname.

La funcionalidad safe-level de Ruby 1.8.6 hasta la versión 1.8.6-420, 1.8.7 hasta la 1.8.7-330 y 1.8.8dev permite a atacantes, dependiendo del contexto, modificar cadenas de texto a través del método Exception#to_s method, como se ha demostrado cambiando el pathname previsto.
