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.

Recommendations For versions prior to 5.6.4, update to version 5.6.4 or later to resolve the issue.
