Description

A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17 and 1.11.x and 2.x before 2.3.0 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.
