.eslintrc is incorrectly resolved from within another .eslintrc file

What version of ESLint are you using? 2.13.0

What parser (default, Babel-ESLint, etc.) are you using? None

Please show your full configuration: The following directory tree:

|- src/
|   `- .eslintrc
`-  website/
     ` app/
        ` .eslintrc

What did you do? Please include the actual source code causing the issue. website/app/.eslintrc contains the following:

extends: ../../src/.eslintrc

What did you expect to happen? website/app/.eslintrc to extend src/.eslintrc. This does work when using eslint@2.12.0.

A workaround is to incorrectly remove one ../ from the path.

What actually happened? Please include the actual, raw output from ESLint.

Getting this same issue, seems related to the updates in config-file.js method applyExtends(config, filePath, relativeTo);. Specifically line 384: parentPath = (!isAbsolutePath(parentPath) ? path.join(relativeTo || path.dirname(filePath), parentPath) : parentPath );

Closing this as it is a duplicate of #6450. There should be a patch release today with the fix. Follow #6450 for updates!
