Backdoor in US emergency alert systems

The US-CERT, which is part of the US Department of Homeland Security, warns that security-critical vulnerabilities in US emergency alert systems potentially allow attackers to switch off the systems or misuse them to broadcast arbitrary emergency alerts. The Linux systems are used at TV and radio stations in the US and enable the US government to interrupt ongoing broadcasts when there is an emergency. This is designed to allow the US president to address the nation within ten minutes.
