Improper sanitization of delegated role names

Impact

The tough library, prior to 0.12.0, does not properly sanitize delegated role names when caching a repository, or when loading a repository from the filesystem. When the repository is cached or loaded, files ending with the .json extension could be overwritten with role metadata anywhere on the system.

AWS would like to thank https://github.com/jku for reporting this issue.

Patches

A fix is available in version 0.12.0.

Workarounds

No workarounds to this issue are known.
