Problem Description:

A researcher has notified us of a DoS attack applicable + to another operating system. While FreeBSD may not be + vulnerable to that exact attack, we have identified several + places where inadequate DoS protection could allow an + attacker to consume system resources.

It is not necessary that the attacker be able to establish + two-way communication to carry out these attacks. These + attacks impact both IPv4 and IPv6 fragment reassembly.

Impact:

In the worst case, an attacker could send a stream of + crafted fragments with a low packet rate which would consume + a substantial amount of CPU.

Other attack vectors allow an attacker to send a stream + of crafted fragments which could consume a large amount of + CPU or all available mbuf clusters on the system.

These attacks could temporarily render a system unreachable + through network interfaces or temporarily render a system + unresponsive. The effects of the attack should clear within + 60 seconds after the attack stops.
