Description:
 An issue was discovered in Symfony before 2.7.38, 2.8.31, 3.2.14, 3.3.13,
 3.4-BETA5, and 4.0-BETA5. The Intl component includes various bundle
 readers that are used to read resource bundles from the local filesystem.
 The read() methods of these classes use a path and a locale to determine
 the language bundle to retrieve. The locale argument value is commonly
 retrieved from untrusted user input (like a URL parameter). An attacker can
 use this argument to navigate to arbitrary directories via the
 dot-dot-slash attack, aka Directory Traversal.
