Forescout researchers have discovered 33 vulnerabilities affecting four open source TCP/IP (communications) stacks used in millions of connected devices worldwide.
Collectively dubbed Amnesia:33 because they primarily cause memory corruption, these vulnerabilities may allow attackers to remotely compromise devices, execute malicious code, perform denial-of-service attacks, steal sensitive information or inject malicious DNS records to point a device to an attacker-controlled domain.
