Descriptions
A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses.
Se ha encontrado un fallo en la pila SCTP de Linux. Un atacante ciego puede ser capaz de matar una asociación SCTP existente mediante trozos no válidos si el atacante conoce las direcciones IP y los números de puerto que están siendo usados y el atacante puede enviar paquetes con direcciones IP falsas
