DESCRIPTION

* TCP forward retransmission timeout bugs leading to resource exhaustion.

Several flaws in the F-RTO (forward retransmission timeout) implementation 
in 2.6.24 which causes packets under certain circumstances to get silently 
dropped while the client will accept longer and longer re-transmit 
timeouts.  This can lead to resource exhaustion and thus to a denial of 
service vulnerability.
