Prerequisites
This type of an attack requires the attacker to be able to generate fragmented IP traffic containing crafted data.
Mitigations
This attack may be mitigated by changing default cache sizes to be larger at the OS level. Additionally rules can be enforced to prune the cache with shorter timeouts for packet reassembly as the cache nears capacity.
