Doc Text:
A flaw was found in golang.org/x/crypto/ssh/agent. An attacker could provide specially crafted inputs that, when processed, lead to the creation of an ed25519.PrivateKey by casting malformed wire bytes. This improper input handling can cause the program to panic and crash, resulting in a Denial of Service (DoS) for the affected component.
