CVE-2008-2464

Estado: ModificadaAlta (7.1)—

The mld_input function in sys/netinet6/mld6.c in the kernel in NetBSD 4.0, FreeBSD, and KAME, when INET6 is enabled, allows remote attackers to cause a denial of service (divide-by-zero error and panic) via a malformed ICMPv6 Multicast Listener Discovery (MLD) query with a certain Maximum Response Delay value.
