Descriptions
A flaw was found in jboss-remoting in versions before 5.0.20.SP1-redhat-00001. A malicious attacker could cause threads to hold up forever in the EJB server by writing a sequence of bytes corresponding to the expected messages of a successful EJB client request, but omitting the ACK messages, or just tamper with jboss-remoting code, deleting the lines that send the ACK message from the EJB client code resulting in a denial of service. The highest threat from this vulnerability is to system availability.
Se ha encontrado un fallo en jboss-remoting en versiones anteriores a 5.0.20.SP1-redhat-00001. Un atacante malicioso podría causar que los hilos (subprocesos) se quedaran detenidos para siempre en el servidor EJB al escribir una secuencia de bytes correspondientes a los mensajes esperados de una petición de cliente EJB con éxito, pero omitiendo los mensajes ACK, o simplemente manipulando el código de jboss-remoting, borrando las líneas que envían el mensaje ACK del código del cliente EJB, resultando en una Denegación de Servicio. La mayor amenaza de esta vulnerabilidad es la disponibilidad del sistema
