Overview

Affected versions of this package are vulnerable to Information Exposure due to the use of the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag. An attacker can exploit deterministic behavior in cryptographic operations to observe a noticeable step in nonce size from 513 to 512 bits, leading to potential timing side-channel information leaks.
