CVE-2008-3655
Summary

Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 does not properly restrict access to critical variables and methods at various safe levels, which allows context-dependent attackers to bypass intended access restrictions via (1) untrace_var, (2) $PROGRAM_NAME, and (3) syslog at safe level 4, and (4) insecure methods at safe levels 1 through 3.

Summary

Ruby versiones 1.8.5 y anteriores, versiones 1.8.6 hasta 1.8.6-p286, versiones 1.8.7 hasta 1.8.7-p71, y versiones 1.9 hasta r18423, no restringe apropiadamente el acceso a variables y métodos críticos en varios niveles seguros, lo que permite a los atacantes dependiendo del contexto omitir las restricciones de acceso previstas por medio de (1) untrace_var, (2) $PROGRAM_NAME, y (3) syslog en nivel seguro 4 y (4) métodos no confiables en los niveles seguros 1 a 3.
