How to fix?

Upgrade cryptopp to version 5.6.4 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. The timing attack protection in Rijndael::Enc::ProcessAndXorBlock and Rijndael::Dec::ProcessAndXorBlock in Crypto++ (aka cryptopp) before 5.6.4 may be optimized out by the compiler, which allows attackers to conduct timing attacks.
