Description:
FreeBSD has acknowledged a vulnerability, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error within the "icmp6_mtudisc_update()" function in src/sys/netinet6/icmp6.c when processing ICMPv6 "Packet Too Big" messages. This can be exploited to cause the IPv6 stack to panic by sending specially crafted ICMPv6 messages to a vulnerable system.
Note: The vulnerability only affects systems with IPv6 support.
