CERT Coordination Center (CERT/CC) has released information on Wi-Fi Protected Access II (WPA2) protocol vulnerabilities. Exploitation of these vulnerabilities could allow an attacker to take control of an affected system.
The vulnerabilities are in the WPA2 protocol, not within individual WPA2 implementations, which means that all WPA2 wireless networking may be affected. Mitigations include installing updates to affected products and hosts as they become available. US-CERT encourages users and administrators to review CERT/CC's VU #228519.
