Advisory

Versions of Cryptograph starting from 35.0.0 are susceptible to a security flaw in the POLY1305 MAC algorithm on PowerPC CPUs, which allows an attacker to disrupt the application's state. This disruption might result in false calculations or cause a denial of service. The vulnerability's exploitation hinges on the attacker's ability to alter the algorithm's application and the dependency of the software on non-volatile XMM registers.
