What is CVE-2009-0687?
The vulnerability exists in the pf_test_rule function found within the OpenBSD Packet Filter (PF) used across various operating systems. It enables remote attackers to induce a denial of service condition by sending specifically crafted IPv4 packets containing an ICMPv6 payload, which can lead to a NULL pointer dereference and ultimately, system panic. This affects OpenBSD versions 4.2 through 4.5, specific versions of NetBSD, and other related systems.
