TYPO3 ke_search path traversal due to lack of normalization on config directory from file indexer

Description

In TYPO3 faceted fulltext search (ke_search), the file indexer does not normalize the configured directory path. A backend user with permission to edit indexer configurations can index documents from arbitrary locations on the server file system through path traversal sequences. This has been patched in versions 7.0.1, 6.6.1, 5.6.2 and 4.6.7.
