CVE-2009-0687

Estado: ModificadaAlta (7.8)—

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.
