cryptography: Cryptography: Buffer overflow via non-contiguous buffer in API

A flaw was found in the cryptography library. This vulnerability occurs when a non-contiguous buffer is passed to certain application programming interfaces APIs that accept Python buffers, such as Hash.update. A remote attacker could exploit this to cause a buffer overflow, potentially leading t...
