Descriptions
The openssl extension in Ruby 2.x does not properly maintain the state of process memory after a file is reopened, which allows remote attackers to spoof signatures within the context of a Ruby script that attempts signature verification after performing a certain sequence of filesystem operations. NOTE: this issue has been disputed by the Ruby OpenSSL team and third parties, who state that the original demonstration PoC contains errors and redundant or unnecessarily-complex code that does not appear to be related to a demonstration of the issue. As of 20140502, CVE is not aware of any public comment by the original researcher

NOTA: este problema ha sido disputado por el equipo OpenSSL de Ruby y terceras partes, que dicen que la demostración PoC original contiene errores y código redundante o innecesariamente complejo que no parece estar relacionado con una demostración del problema. Desde 02052014, CVE no está consciente de ningún comentario público por parte del investigador original.
