Details

Yuval Yarom and Katrina Falkner discovered a timing-based information leak,
known as Flush+Reload, that could be used to trace execution in programs.
GnuPG and Libgcrypt followed different execution paths based on key-related
data, which could be used to expose the contents of private keys.
