The original RST-based attack was against a mixed Cisco/Linux+Quagga environment, IIRC. This combination is especially vulnerable if the BGP connection is established in the right direction.
However, nobody has probably bothered to replicate that attack in the lab. As published, the attack just doesn't work against Cisco/Cisco peerings. Unfortunately, there is another that *might* actually work, that's why there was so much fuss about it.
If you have some window checking bugs (like the BSDs had), it can be quite worse, of course. But such issues are usually way overrated. Most DoS potential remains unexploited anyway, and I don't think the disruption from people frantically enabling the TCP MD5 option payed off in the end. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
