Description: The TCP/IP stack of Packeteer PacketShaper is generating
predictable initial sequence numbers (ISN): The sequence number is
incremented by 128000 per second and by 64000 per connection. (As an
example, if the current SYN/ACK ISN is 319104000 then about six seconds
later the ISN is likely to be 319936000.) This allows an attacker to spoof
connections from trusted clients or launch a DoS attack.
This type of vulnerability has been described over ten years ago in:
The vulnerability has been identified in versions 7.3.0g2 and 7.5.0g1.
