"summary": "Denial of service via crafted Signer in golang.org/x/crypto/ssh",
"details": "Attackers can cause a crash in SSH servers when the server has been configured by passing a Signer to ServerConfig.AddHostKey such that\n1) the Signer passed to AddHostKey does not implement AlgorithmSigner, and\n2) the Signer passed to AddHostKey returns a key of type “ssh-rsa” from its PublicKey method.\n\nServers that only use Signer implementations provided by the ssh package are unaffected.",
