| Doc Text: |
A flaw was found in OpenSSH. This vulnerability allows the system to use unintended Elliptic Curve Digital Signature Algorithm (ECDSA) algorithms. This occurs because the configuration for accepted public key algorithms is misinterpreted, leading to the use of weaker cryptographic methods than intended. This could potentially allow an attacker to compromise the confidentiality of data.
