Descriptions

The regular expression engine (regex.c) in Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 allows remote attackers to cause a denial of service (infinite loop and crash) via multiple long requests to a Ruby socket, related to memory allocation failure, and as demonstrated against Webrick.

El motor de expresiones regulares (regex.c) en Ruby 1.8.5 y anteriores, 1.8.6 a través de p286-1.8.6, 1.8.7 a través de 1.8.7-p71, y 1.9 a través de r18423 permite a atacantes remotos provocar una denegación de servicio (bucle infinito y caida) a través de múltiples peticiones largas a un socket de Ruby. Esta denegación de servicio esta relacionada con un fallo en la asignación de memoria, como se ha demostrado contra Webrick.
