Descriptions

The pf_test_rule function in OpenBSD Packet Filter (PF), as used in OpenBSD 4.2 through 4.5, NetBSD 5.0 before RC3, MirOS 10 and earlier, and MidnightBSD 0.3-current allows remote attackers to cause a denial of service (panic) via crafted IP packets that trigger a NULL pointer dereference during translation, related to an IPv4 packet with an ICMPv6 payload.

La función pf_test_rule de OpenBSD Packet Filter (PF), tal como es usada en OpenBSD v4.2 hasta v4.5, NetBSD v5.0 anterior a RC3, MirOS v10 y anteriores y MidnightBSD v0.3 hasta la versión actual permite a atacantes remotos causar una denegación de servicio a través de paquetes IP modificados que provocan una "desreferencia" de un puntero nulo relacionada con un paquete IPv4 con datos ("payload") ICMPv6.
