It's often riddled with vulnerabilities, it's difficult to update with patches, and it's increasingly the target of real-world attacks. Now a well-intentioned mechanism to easily update the firmware of Dell computers is itself vulnerable as the result of four rudimentary bugs. And these vulnerabilities could be exploited to gain full access to target devices. The new findings [...]
