Security
* An adversary with access to precise enough information about memory
accesses (typically, an untrusted operating system attacking a secure
enclave) could recover an RSA private key after observing the victim
performing a single private-key operation if the window size used for the
exponentiation was 3 or smaller. Found and reported by Zili KOU,
Wenjian HE, Sharad Sinha, and Wei ZHANG.
