libssh is vulnerable to Denial Of Service (DoS). The vulnerability is due to a lack of proper validation and checking of return values in the abstract layer for message digest (MD) operations implemented by different supported crypto backends. This could lead to low-memory failures and potentially leads to Denial of Service (DoS). resulting in dropped connections.
