A vulnerability, which was classified as critical, was found in OpenBSD 3.0/3.1/3.2/3.3/3.4 (Operating System). Affected is an unknown code of the component Packet Filter. The manipulation with an unknown input leads to a authentication spoofing vulnerability. CWE is classifying the issue as CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
PF in certain OpenBSD versions, when stateful filtering is enabled, does not limit packets for a session to the original interface, which allows remote attackers to bypass intended packet filters via spoofed packets to other interfaces.
