NVD Description
Note: Versions mentioned in the description apply only to the upstream libcrypto++ package and not the libcrypto++ package as distributed by Ubuntu.
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.
