The U.S. Department of Homeland Security (DHS) has warned of critical security vulnerabilities in Emergency Alert System (EAS) encoder/decoder devices.

If left unpatched, the issues could allow an adversary to issue fraudulent emergency alerts over TV, radio, and cable networks.

The August 1 advisory comes courtesy of DHS’ Federal Emergency Management Agency (FEMA). CYBIR security researcher Ken Pyle has been credited with discovering the shortcoming.
