Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in Juniper Junos. A remote user can consume excessive resources on the target system.

A remote user can establish a TCP connection with the target device and then cause the connection to transition to the LAST_ACK state while the target daemon is not finished sending data to cause the socket to get stuck in the LAST_ACK state.
