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.
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
