Descriptions

A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

Se detectó un fallo en ghostscript, versiones 9.x versiones anteriores a la 9.50, en el procedimiento setsystemparams donde no aseguraba apropiadamente sus llamadas privilegiadas, permitiendo a los scripts omitir las restricciones "-dSAFER". Un archivo PostScript especialmente diseñado podría deshabilitar la protección de seguridad y entonces tener acceso al sistema de archivos o ejecutar comandos arbitrarios.
