Intel chip flaw: Math unit may spill crypto secrets to apps – modern Linux, Windows, BSDs immune
A security flaw within Intel Core and Xeon processors can be potentially exploited to swipe sensitive data from the chips' math processing units.
Malware or malicious logged-in users can attempt to leverage this design blunder to steal the inputs and results of computations performed in private by other software.
These numbers, held in FPU registers, could potentially be used to discern parts of cryptographic keys being used to secure data in the system. For example, Intel's AES encryption and decryption instructions use FPU registers to hold keys.
