Three vulnerabilities have been identified in the Linux Kernel 2.4 branch. One can be exploited to cause a Denial of Service by a malicious person and is very similar to the recent Linux Kernel Denial of Service. The others are local Denial of Service vulnerabilities.
The remote Denial of Service is possible, because malicious people can cause hash table collisions by sending a stream of maliciously crafted fragmented TCP packets. This will cause the system to consume large amounts of CPU resources.
