DISPUTED In Libgcrypt 1.8.4, the C implementation of AES is
vulnerable to a flush-and-reload side-channel attack because physical
addresses are available to other processes. (The C implementation is used
on platforms where an assembly-language implementation is unavailable.)
NOTE: the vendor’s position is that the issue report cannot be validated
because there is no description of an attack.
