A vulnerability in the pf_test_rule function of the OpenBSD Packet Filter (PF), present 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 trigger a kernel panic by sending specially crafted IP packets. The issue arises from a NULL pointer dereference during packet translation when an IPv4 packet contains an ICMPv6 payload, leading to a system crash.
