Name of the Vulnerable Software and Affected Versions Crypto++ versions prior to 5.6.4

Description The issue concerns the timing attack protection in the Rijndael encryption and decryption processes. Specifically, the Rijndael::Enc::ProcessAndXorBlock and Rijndael::Dec::ProcessAndXorBlock functions may have their timing attack protection optimized out by the compiler. This optimization could allow attackers to conduct timing attacks.
