Summary
A cryptographic cache-based side channel in the RSA implementation in Botan through 1.10.16, and 1.11.0 through 2.2.0, allows a local attacker to recover information about RSA secret keys, as demonstrated by CacheD. This occurs because an array is indexed with bits derived from a secret key.
