CVE-2008-2464
HighSummary
Funkcja mld_input w jądrze NetBSD 4.0, FreeBSD i KAME, gdy włączony jest INET6, pozwala zdalnym atakującym na wywołanie odmowy usługi (błąd dzielenia przez zero i panika) poprzez źle sformułowane zapytanie ICMPv6 Multicast Listener Discovery (MLD) z określoną wartością Maximum Response Delay.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zdalnego zablokowania systemu, co prowadzi do przerwy w dostępności usług. Może to wpłynąć na stabilność i bezpieczeństwo infrastruktury sieciowej organizacji.
Recommendation
Zaleca się aktualizację systemów do najnowszych wersji, które eliminują tę podatność oraz monitorowanie ruchu ICMPv6 w celu wykrywania potencjalnych ataków.

Original NVD description (English source)
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.
