"'KeyTrap' DNS Bug Threatens Widespread Internet Outages"
Researchers recently discovered a fundamental design flaw in a Domain Name System (DNS) security extension that could lead to widespread Internet outages. The security vulnerability, called KeyTrap and tracked as CVE-2023-50387, was discovered by a team from the Germany-based ATHENE National Research Center for Applied Cybersecurity. According to the team, a single packet sent to a DNS server implementation using the DNSSEC extension to validate traffic could cause the server to enter a resolution loop, consuming all of its own computing power and stalling.
