"summary": "Panic due to improper verification of cryptographic signatures in golang.org/x/crypto/ssh",
"details": "An attacker can craft an ssh-ed25519 or sk-ssh-ed25519@openssh.com public key, such that the library will panic when trying to verify a signature with it. If verifying signatures using user supplied public keys, this may be used as a denial of service vector.",
