| Doc Text: |
A flaw was found in Nokogiri, an open source XML and HTML library for the Ruby programming language. A remote attacker could exploit this vulnerability by calling specific methods on allocated-but-uninitialized native wrapper classes that inherit from `Nokogiri::XML::Node`. This could lead to a NULL pointer dereference, causing the process to crash and resulting in a Denial of Service (DoS).
