Description:
A security issue has been reported in FreeBSD, which can be exploited by malicious people to cause a DoS (Denial of Service).
The security issue is caused due to an error within the processing of packets with IPv6 type 0 route headers. This can be exploited to cause a DoS due to high network traffic by sending specially crafted IPv6 packets to vulnerable systems.
