Descriptions

A flaw was found in iperf, a utility for testing network performance using TCP, UDP, and SCTP. A malicious or malfunctioning client can send less than the expected amount of data to the iperf server, which can cause the server to hang indefinitely waiting for the remainder or until the connection gets closed. This will prevent other connections to the server, leading to a denial of service.

Se encontró una falla en iperf, una utilidad para probar el rendimiento de la red mediante TCP, UDP y SCTP. Un cliente malicioso o que no funciona correctamente puede enviar menos cantidad de datos de la esperada al servidor iperf, lo que puede hacer que el servidor se cuelgue indefinidamente esperando el resto o hasta que se cierre la conexión. Esto evitará otras conexiones al servidor, lo que provocará una denegación de servicio.
