+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.
