Descriptions

Ruby 1.8.7 before patchlevel 371, 1.9.3 before patchlevel 286, and 2.0 before revision r37068 allows context-dependent attackers to bypass safe-level restrictions and modify untainted strings via the name_err_mesg_to_str API function, which marks the string as tainted, a different vulnerability than CVE-2011-1005.

Ruby v1.8.7 antes de patchlevel 371, v1.9.3 antes patchlevel 286 y v2.0 antes de la revisión r37068 permite a atacantes dependientes de contexto evitar las restricciones de seguridad de nivel y modificar cadenas untainted a través de la función de la API name_err_mesg_to_str, que marca la cadena como contaminada, una diferente vulnerabilidad a CVE-2011-1005.
