gEDA-bug: [Bug 700333] Re: Local configuration should be parsed, not evaluated



Spec looks ok - I guess you wanted it to map nicely to GKeyFile or similar "ini" file structure.
How about Scheme hooks? s-expr evaluation would be difficult here, and config file would accommodate this type of data.
Maybe a config value with list of extra Scheme files to load - it would have to be forbidden/ignored in the "per project" configuration context.

Title:
  Local configuration should be parsed, not evaluated

Status in GPL Electronic Design Automation tools:
  Confirmed

Bug description:

   security yes
   private no
   done

  Currently, per-directory rc files are evaluated as Scheme scripts.  This
  is an arbitrary code execution security risk.  For example, users (and
  in particular *new* users) are likely to want to download and open
  designs from elsewhere, and almost all designs include a 'gafrc' file to
  set up per-project component libraries.

  Instead of being evaluated, local configuration files should be parsed.
  This way it would be much harder to craft malicious designs.

  An example of a parsable configuration file format is the resource file
  format used by PCB.

  In addition, a tool should be developed for migrating existing designs'
  rc files to the any configuration system.
