Description

A flaw was found in Nokogiri, an XML and HTML library for Ruby. When an attacker provides an invalid encoding to the Document#encoding= function, the library frees the document's current encoding string without replacing it. This leaves the document referencing freed memory, which can lead to a denial of service (DoS) due to a segmentation fault or information disclosure by leaking freed memory into a Ruby String.
