DSA-537-1 ruby -- permisos inseguros de archivo

Fecha del informe:

16 de ago de 2004

Paquetes afectados:

ruby

Vulnerable:

Sí

Referencias a bases de datos de seguridad:

En el sistema de seguimiento de errores de Debian: error 260779.
En el diccionario CVE de Mitre: CVE-2004-0755.

Información adicional:

Andres Salomon avisó de un problema en la gestión de sesiones CGI de Ruby, un lenguaje de guiones orientado a objetos. Las implementaciones de FileStore (y presuntamente de PStore, pero no en Debian woody) de PCGI::Session almacenaban de forma insegura la información de la sesión. Simplemente creaban los archivos, no teniendo en cuenta los permisos. Esto podía provocar que un atacante que también tuviera acceso por shell al servidor web tomara el control de la sesión.

Para la distribución estable (woody), este problema se ha corregido en la versión 1.6.7-3woody3.

Para las distribuciones inestable y en pruebas (sid y sarge), este problema se ha corregido en la versión 1.8.1+1.8.2pre1-4.

Le recomendamos que actualice el paquete libruby.

Arreglado en:

Debian GNU/Linux 3.0 (woody)
