Description
In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, the Dir.open, Dir.new, Dir.entries and Dir.empty? methods do not check NULL characters. When using the corresponding method, unintentional directory traversal may be performed.
It was found that the methods from the Dir class did not properly handle strings containing the NULL byte. An attacker, able to inject NULL bytes in a path, could possibly trigger an unspecified behavior of the ruby script.
